Download With Bittorrent?

Category: File-Sharing , Software

I've been told that I can download movies and even popular software for free using Bittorrent. Sounds too good to be true… What exactly is Bittorrent, is it legal, and safe to use?

What is Bittorrent?

BitTorrent is two things, depending on how many pencils you have in your pocket protector. In technical terms, BitTorrent is a peer-to-peer (P2P) platform designed to deliver large files over the over the web. The BitTorrent file distribution protocol was created by programmer Bram Cohen to distribute large amounts of data by relying on an ad-hoc network of individual users (peers) instead of expensive servers and bandwidth resources. In a nutshell, BitTorrent speeds up the download time by getting smaller chunks of large files from many different sources. A more popular file can be downloaded faster, because many people will be downloading it at the same time, while also uploading the data to other users.

BitTorrent is also a software program that provides Internet users with downloadable digital content such as films, music, games, podcasts and software. To use BitTorrent , one needs to install a BitTorrent client, a free software program that implements the BitTorrent protocol. The client has the capacity to prepare, request and transmit any type of computer file over a network.

Downloading BitTorrent

Based on your operating system and computer horsepower, many BitTorrent clients are available for download.

  • The original and official BitTorrent client, written by Bram Cohen himself, lacks a fancy graphical interface, but it downloads quickly, is popular with technies, and is available for Windows, Mac, Linux and other Unix-like systems.
  • Azureus is a very popular BitTorrent client, and because it's written in the Java language, will run on Windows, Mac or Linux systems.
  • Lately, uTorrent has been growing in popularity because of the wide range of features offered, small size and efficient memory usage. uTorrent allows multiple simultaneous downloads, can resume interrupted transfers, and is available in many languages. uTorrent (pronounced like "micro torrent") is available only for Windows 95, 98/ME, NT/2000, XP and above.

But beware... some BT clients like BitLord and eDonkey have been known to contain adware. Always download from a reputable source, and use both anti-virus and anti-spyware protection. (Read more about virus and spyware protection.)

How Does BitTorrent Work?

While sharing the large files over the internet, the usual problems faced are bandwidth constraints, upload limits and other problems peculiar to the internet. To tackle this problem, BitTorrent breaks a large file into number of pieces, or torrents. To recognize each piece, the software tags it with a checksum (sort of a digital fingerprint) and records it in the torrent file. When the file is being downloaded, the checksums in the original files are compared with the checksums in the received file to make sure that the file is complete and error-free.

A typical BitTorrent file will contain an 'Announce' section, which specifies the file names and length of each individual piece. The person wishing to make a file available can place a link to the file on a website. Users who want to download a specific file can browse or search the web, then click the download link, which opens the BitTorrent client to begin the download. While downloading a file, the BitTorrent program connects not only to the link, but also to other peers who have the same file. This way, sharing of network resource is maximized and the download becomes faster and more reliable.

One criticism of BitTorrent is that the benefits of the P2P sharing can break down as more and more people have the beginning of a file, and no one has the end. Download speeds can slow to a crawl in such a situation. And for files that are not often downloaded, it can actually take much longer than a direct download because BitTorrent is optimized for downloading in a many-to-one environment.

There are also reports from Internet service providers that BitTorrent and other P2P traffic is consuming 60 percent or more of all Internet bandwidth. Granted BitTorrent is just a protocol, and as such is neither good nor evil. But it stands to reason that most BitTorrent traffic is illegal downloading of copyrighted materials. Couple that with the high costs of bandwidth, and you can understand why some ISPs are banning or throttling P2P usage.

Some popular BitTorrent search engines can be found at BitTorrent.com, Torrent Spy, and MiniNova.

How is BitTorrent Different?

You may think that BitTorrent sounds quite similar to Limewire and other P2P filesharing tools. From the perspective of the average user, they do pretty much the same thing. But behind the scenes, one significant technical difference is that BitTorrent requests and receives files from multiple sources, while other P2P technologies download the file from a single source. Also, BitTorrent is designed to move the more popular files through the network faster, because BitTorrent is simultaneously downloading chunks of the file to your computer while uploading it other users.

BitTorrent also seems to be the tool of choice for downloading movies and television shows, while Limewire offers more content in the music arena.

Legal Issues

Is BitTorrent legal? This morning I downloaded a full-length movie, "The Man Who Knew Too Much", directed by Alfred Hitchcock. Since this was the 1934 version, which is now in the public domain, there are no legal or copyright issues. But make no mistake, the availability of copyrighted and pirated materials is rampant on BitTorrent . There are differing opinions on whether or not it's ethically wrong to download the latest episode of "Desperate Housewives" and watch it on your home computer. There's less wiggle room when it comes to downloading a pirated copy of a movie that's playing in the theatre down the road.

And the entertainment industry's lawyers are becoming more and more aggressive when it comes to protecting their interests. The companies that use BitTorrent file sharing are now in the crosshairs of the Motion Picture Association, the Recording Industry Association, government agencies and media production companies. In the recent past, websites such as supernova.org and Lokitorrent.com that used BitTorrent technology were shut down because of government orders or litigation. Even individuals are being targetted, in a sometimes chilling manner. One person told me this:

"I visit a torrent site weekly to download this week's episode of my two favorite tv shows, House M.D. and The Apprentice. I work on the nights that both shows air on national tv, so I download a torrent file of each. To me, this is no different that setting the VCR to record something while I'm at work... but the benefit with a torrent file is that it takes up a lot less space than a video tape. I received a letter from my cable internet provider, who was contacted by NBC Universal saying that they'd tracked illegal downloading of a HOUSE MD file. It was a 'cease and desist' letter notifying me that, essentially, NBC was 'on' to me, and if they so chose, they could take me to court for pirating copyrighted material."

The latest controversy involving BitTorrent is the allegation by Microsoft that unauthorized copies of its latest operating system, Vista were available on a BitTorrent web site, much before the official release of the product. Although Vista was officially launched on January 29, cracked copies of Vista were available on BitTorrent much earlier. Cracked copies of Microsoft Office 2007 were also available on the BitTorrent web site.

In its defense, BitTorrent argues that it only facilitates the sharing of the file by placing a link. It does not actually store or share the files and hence, it cannot be held responsible for any illegal activities. But the companies which are affected by BitTorrent programs, beg to differ. Certainly they stand to lose a great deal of revenue if people can easily download illegal copies of their products. This is sure to be a hotbed of legal wrangling for some time to come. In the meantime, be careful what you download!

Has anybody got any letters/calls for downloading music on Bittorrents? I realize that it's strictly not legal, but it seems that most internet providers are going after those downloading movies/shows... Any info. is appreciated.

EDITOR'S NOTE: It's not the ISPs that are going after the infringers -- it's the movie and TV content producers. And yes, it happens with music as well.

If I have songs downloaded from bearshare, etc. from over 2 years ago on my computer, but never allowed sharing of my files, am I still in danger of being sued? I quit downloading songs on p2p networking the moment I heard about people getting arrested, however, still utilize the songs for my own usage. thanx,ginny

EDITOR'S NOTE: My guess is that as long as you don't let those songs leave your computer, you should not be in danger of being sued. It's still possible that your ISP might go through their logs from that time period, if they were asked to do so as part of a legal "discovery" process, and smack your wrists for downloading, whether they are still on your hard drive or not. Not very likely, though, I'd think.

ok so what about people like me who dont use such programs as uttorrent bearshare emule etc, etc, but directly download files that has been paid via paypal. i legaly pay for my video tutorials some of these can be 3 gigs big and take about 20 mins to download. the sites i download from are digital tutors gnomon and gnomonology, how will the isp`s going to tell the difference...

EDITOR'S NOTE: You have no need to worry. Your ISP can tell the difference.

Okay, I had to stop downloading torrents from BitTorrent from home because Cox suspended my internet (twice) until I personally called them. If I download my torrents off of public WiFi connectoins (my college/Starbucks/airports), and keep the files on a portable hard drive, can I be personally tracked? Can they link my IP address to my personal information?

EDITOR'S NOTE: Any wifi that requires a login/password will be trackable. Anonymous wifi is much less likely, although there may be some gotchas with cookies. But downloading large files over public wifi is rather anti-social, due to the bandwidth you'll be consuming.

If this is the first time I am downloading something via bittorrent am I still going to get one of those calls/letters/emails? I got an album released yesterday... I would buy it but it's only available in Europe or on the internet but I don't have a credit card or anything like that. I don't want to download anything else, it was just for this one thing. Am I still at risk?

I live in a country in SE Asia and use bittorrents to stay up with a couple of shows that I like. What are international ramifications with bittorrent use?

EDITOR'S NOTE: It depends on the local government, I suppose. I wouldn't do it in China...

I downloaded a movie and a game in the past little while and got emails from both, does this mean I can't download anymore without getting more emails? If I move away will I be able to download again?

EDITOR'S NOTE: It means they're on to you... take it as a warning. If you switch to another ISP, you might buy yourself some time, but ISPs could very well be sharing lists of "bad customers". Is it really worth losing your Internet connection and possible legal troubles?

In most jurisdictions prostitution is illegal. If a person who I don't even know is looking for a woman, and I find him one and not only make their transaction possible, but I profit from it, what does that make me? I belive the term would be a pimp. And I could and would be arrested for it if caught. And the prostitute would be charged. And the john would be charged. So, apply that analogy to Bittorrent. Why shouldn't the downloader, the file provider(s) and Bittorrent all be indictable?

How about signing up anonymously for bittorrent service on public wifi, then do all your serious downloading via public wifi? No IP number, no snoopy ISP.

Derrick's analogy implies that BitTorrent (whomever that may be) is making a profit from the downloading activity. Is that true, and if so, how?

EDITOR'S NOTE: Bittorrent is not a who. It's a network protocol upon which software can be built to transfer large files in an efficient manner. Bittorrent clients (the software) are generally freeware, open source collaborative projects.

I was told that I could hide my down loading from sites such as The Pirate Bay & IsoHunt by using a program called PeerGuardian2. Has any one out there checked into this and if so what are your opinions?

Thanks ...

In 1984 the U.S. Supreme Court held that, in Sony v. Universal Studios (the Betamax Case), the potential for copyright infringement was not prima facie evidence of de facto infringement. Essentially, the VCR "became" legal to use. The price of blank tapes plummeted from $14.00 ($30.00 in 2009 dollars) to $1.50 today. No longer were fees being collected for "copyright distribution", a specious claim anyway since it was unknown which programs were being recorded.

As recently as June 2005, the entertainment industry has been suing to overturn the Betamax Case in order to set precedent for other lawsuits concerning P2P technology, and have been chipping away at it, nonetheless.

The legal principle for copyright protection is laudable and noble, but the legal implementation of it has been nothing more than a heavy-handed protection of a mafia-style fiefdom to protect its own profits, using an image of a poor, deprived artist as its poster boy, no more realistic than an artist's rendition of Little Boy Blue.

If the industry were truly concerned with copyright protection for the artists (and itself), then it would embrace and adapt the new technology to its own benefit. But that would require negotiation and a sharing of profits. In the world of the Mafia, nobody gets away with skimming, no matter how small, and the penalty is severe for even thinking about it.

In my opinion, any game over 10 years or older should be able to be downloaded freely.

EDITOR'S NOTE: How about any car over 10 years old... can we steal them too?

i have been using bit torrent for a few years, but not alot and every day. just casually to get a few movies here and there to watch on my ipod when im bored. recently i downloaded the robin hood 2010 movie and i had a lot of other programs/misc stuff i was downloading and on thanksgiving i figured i wont be home so i should leave it on all day and let all my downloads finish.
today i got a letter from my internet provider saying i was downloading copyrighted material (robin hood (2010)) and warned me. its pretty scary guys. but how do they catch you if your downloading only a little bit from different people?
maybe they sent a bug with the chunk of file they sent to your computer to (track)/backdoor/hack/virus/w/e and there for catch you. but if they did that wouldnt that be an illegal act as well? other wise how do they catch you?

As long as films, TV and music are for private use, how can one differentiate between borrowing a CD/DVD from a friend/neighbour and borrowing from someone over the internet?

Most of us will buy the things we like and can afford, and often rent first, when we can. It is good to have an opportunity to to decide whether we want to commit to buying first, and would you buy anything else without seeing or trying it first.

In my experience, I don't see why I should buy an album or a film, without trying it, I would not buy an item of clothing based on a fabric swatch or buy a CD based on a 30 sec clip.

There are benefits to the industry, people who are budgeting, and choosing their products can look, try and decide where to spend their money. If they don't buy it after seeing/hearing it. they were never going to do so in the first place, but may actually pass on a recommendation to someone that it may suit.

Why on earth should (particularly) the film industry expect to be treated with kid gloves and not allow the consumer to decide if it is worth the outlay. Other items need to be checked for suitability, and deemed fit for purpose?

I understand the effect of piracy and illegitimate sales, but to criminalise people for wanting to enjoy and sample products is madness.

Please stick to illegal sales and allow individuals to explore their options.
