If you enjoy watching TV on your computer and are looking for some extra content, take a look at JLC’s Internet TV. From their website:

JLC’s Internet TV is a FREE program for watching and browsing thousands of TV channels freely available on the internet. It’s probably the biggest and most up to date database of channels ever, and users are able to submit, rate and flag channels. And with the new flagging and rating system you’ll easily see which channels works and which is worth to watch and our goal is to bring you the best online TV experience out there!

Personally, I’m not a big fan of watching TV or video on a computer, but I can see the appeal of this. The only requirement is Windows Media Player and (depending) Real Player. The features are typical of what you would expect from any TV-esque application (favorites, ratings, etc.).

I would be really interested to see if anyone has tried this and what the opinions are.
