Sound and video blurred with ATI dual xinerama

[Robert Fitzpatrick]

After installing the ATI driver from the ATI site,
ati-driver-installer-9-9-x86.x86_64.run, and setting up with xinerama
using my dual screens with different resolutions, the sound and video
are blurred. The sound is slowed and stretched out and the video
hesitant. The only way to get smooth sound and video is to return to
single display. Anyone know how I can remedy this in 9.04 or which logs
to look for clues?

Thanks, Robert
