I have been using Ubuntu for over 2 years now and the only thing that I could not get to work properly is the video performance.

The issue is that when I play any video using vlc,totem or mplayer I get strange horizontal white lines(king of watery effect to them)about an inch from the top of the screen.

So I am requesting all people here using the same combination as me i.e Ubuntu 9.10 amd64 + Acer AL1916W + ATI Radeon x1250 with built-in drivers, and are satisfied with their video output, to post their xorg.conf files here so that I can try them.
