You tube

It actually varies from video to video. Many videos are uploaded straight from cellphones and portables. Such videos are unlikely to be very good. Even if a video quality is good, flv format deteriorates it. So try downloading the movie from youtube in Mp4 format and viewing it. You can do it using keepvid.com

I have watched couple of movies in youtube without any disturbance. Only thing is you need to change it everytime. now a days I started watching movies in tamilpeek.com

www.cinetube.es lets you watch movies free but in spanish.

i don't use hulu but i guess they said it was good, then i bet its good, but what i use to watch movies would be, watch-movies.net (best on firefox), and surfthechannel.com (you can watch movies and tv shows and others) thats what i use, i say they're both awesome, but watch-movies.net isn't as good as surdthechannel :)
