I have an X1600 running on Linux 2.6.18 FC6, with ATI's latest drivers 8.37.6

There are no errors in the xorg.0.log file, and ATI's fglrx drivers are reported in fglrxinfo (for regular graphics and OpenGL too). Overall graphics look good.

The problem is that when I playback a DVD, the video (in MythTV) is jerky / stuttery. I'm stumped....anyone know where to turn?

Thanks,
MD
