The only way for it to be illegal is if you're downloading it to your hard drive and keeping it. flash-based online TV streaming is only on your hard drive until you finish watching the show, called a 'buffer' and then once it's over it is deleted.

I wouldn't touch 'torrents' with a 40-foot pole. also using those kinds of P2P programs is just asking for computer viruses.

The sites i posted don't own the videos, they host them from sites like NBC, Hulu, Youtube, etc. so there is no copyright violation.
