xubuntu video rendering issue

As i am playing avi videos on my newly installed Xubuntu i observe video flickering because of which i do not get optimal user experience while watching videos. I have tried multiple players as well as multiple videos but the problem persists. The flickering doesnt exist when i am playing my video on win 7.

info driver:- amd radeon 4500 propriety driver activated players tried:- mplayer, vlc

If you have xubuntu's compositor active (only supports drop shadows and transparency), try running mplayer with -vo gl or -vo gl2. If this does not help, try turning the compositor off (settings/window manager tweaks, rightmost tab).
