About the only show I can make an effort to sit down and devote a half-hour to is the Simpsons. On occasion I'll grab a torrent off the Intarnets and watch something after the fact, but thanks to the advice of my buddy Cam, I recently installed the Azureus bittorrent client, implemented an RSS plugin, and hey presto, the five shows I actually watch get grabbed automatically and dumped into my hard drive.
In case the previous paragraph makes little if any sense, don't worry. Some guy has come up with a small tutorial on how to set this stuff up. And PC guys, don't worry, Azureus is a java program, so it doesn't matter what operating system you use.
