You guys that dont know how to use torrents, I suggest to read up on them before downloading the files. It kinda helps to know what a torrent file is, and how its used. go to http://www.bittorrent.com and read up first.
.torrent files and NOT media files, they are very small files, that link to the actual media file that someone is hosting. You need a seperate program to open the .torrent file to start downloading. I suggest
http://www.torrentstorm.com fairly strait forward. Also the speed of the download depends on how many people are sharing the video file, sort of like how kazza worked. also it usually speeds up after a few mins of downloading. Also torrents work on the theory that you must share or seed the file for a while after downloading. This helps more people getting the file, and the speed of downloading.
If you have used Kazza or any other type of file sharing program, this should be straight forward for you.
