megavideo is best but it has restriction for free members.i would suggest you go for putlocker they offer unlimited access for free users, now i mostly watch movies on putlocker links!
apart from that there are many video streaming sites,
novamov
videoweed
veehd
movshare
divxstage
vidxden
loombo
sockshare
divxme
etc.
Hope it helps a bit.
