.The best place right now is www.hulu.com. Hulu doesn't have too many movies, though. They have tons of television shows. They are in the process of adding more movies. The quality is excellent.

The other place is veoh.com. These people don't host the files. They gather links and embed the videos on their own website. So, most of the television shows you find here are embedded versions of hulu.com or other websites. The quality is good.

If you are interested in watching Nepali movies and tv shows, then go to nepalibergen.googlepages.com. It is a site created by Nepalese students in Bergen, Norway. They have tons of Nepali tv shows and movies. Quality is decent, but hey, you get to watch something in Nepali.
