•¬ Choose a torrent client. . .
There are several out there. In my opinion there are really only two to choose from. Vuze and Utorrent. You can get Vuze from
http://azureus.sourceforge.net/ and you can get Utorrent from
http://www.utorrent.com/. It has been several years from the last time I used Vuze but as I recall, it had several options that can be confusing for the average person. I personally, highly recommend that everyone uses Utorrent. It's fast and easy and the settings are self explanatory.
•¬ Know where you are downloading from. . .
Don't download a torrent from a stupid site that is in Russian. There are only a few good sites out there.
thepiratebay.org
isohunt.com
mininova.org
I would say those are the best, safest, fastest torrent sites out there.
You also have private sites. I personally have never had the need for one other than Demonoid.
Demonoid.com is amazing. However, you need to either A) know someone who can get you a key, or B) check the site regularly for their open registration days. Some other sites out there want you to pay and upload constantly. DO NOT DO IT. It's a scam.
•¬ Know what you're downloading. . .
Download torrents that are active. Use the search and the filters and set it to order by the number of seeders. Look at the top three. One, if not all, will be alright to download. Not so sure? Check the comments. See if people are giving the torrent negative or positive reviews. Also, one of the great things about Utorrent is choosing what you are downloading from a torrent. For example, before the torrent actually starts downloading the files, you have the option to see what is also coming along with the file you are downloading. Do you really need those tracker files that the website throws in there, the sample video of the movie, or the .nfo files? No, well sometimes the .nfo files but majority of the time, no. Uncheck that stuff so that you can enjoy whatever you want to watch, play, or listen to faster.
There is always an exception....
