Pandora.tv, a South Korean video website that has ties to Cyworld (and an English UI) is fairly reliable in America. It can sometimes take 20 seconds or so to buffer up the stream, but I've watched TV shows on it before. Example sports clip.
Tudou.com is completely DCMA proof as it is Chinese and they just laugh at that kind of stuff. The downside it is can be slow. That said, not terribly so, in that if I start a movie buffering, go to the kitchen and make snacks, and come back I have enough buffered to watch without interruption. That said tudou's 30 second load time and intro ads can be annoying when you just want to watch a minute or two of highlights.
