oh ya,
ovguide.com pretty much sums up all the available places that you can watch online streams.
megavideo seems to be popular along with the 2 new chinese hosts, youku and toudu. With how things stand now, i prefer veoh videos if I can watch it on their client (veohtv beta at veoh.com, since you can only review 5 minutes of movies longer than ~24 min)

usually, for all my needs I go to www.nabolister.com  (movies, tv serials, documentary etc)
