screen tearing on videos (not flash videos)

view story

http://askubuntu.com – I mean video files on my hard drive. I get noticeable screen tearing on VLC, Totem, gnome mplayer and Mplayer. I have tried fglrx drivers and now the experimental AMD drivers. I have a Radeon HD6950 and enabling 'tear free' mode in catalyst removes the tearing but makes my videos have a strange motion, like a stuttery framerate. Anyway to fix this? Thanks. (HowTos)
