Ah, something to try. I'm also going to try rolling back to the 2.6.10 kernel. From what I've been reading, there are quite a few issues with the 2.6.11 kernel and ATI's drivers.

Ah whoops, I wasn't reading. Is there any way to get around this without having to recompile my kernel? I've only done that once before and I killed a week in the process.Carl Lewis wrote:
Bingo... I think we've found the culprit. I'm getting the error you mentioned about the DRI module in my xorg log file.I'd lay money you need to recompile the kernel with a few bits as modules instead of built-in. Particularly around the DRI/AGPART (sp?) area. Sorry I'm at work and don't have the details,
Otherwise what was happening to me was that the fglrx driver would give a little error message in the Xorg.0.log about not being able to load DRI. Even though we only need the 2D acceleration the only way I could get good performance on my box (similar to yours) was with all the 3d acceleration enabled, and working. Well except openGL overlay of course, as that won't run at the same time as the XV overlay (don't you love this driver :-( I also had to set the fglrxdriver to use external AGP
Only once all the 3D stuff was working and there were no little hiccups in the X log did my performance return to close to what it was. Not as good, only close. It now runs 30-35% for playback where it was 25-30% (Pentium4 1.5GHz box)
Cheers, Carl.

[drm] failed to load kernel module "fglrx" (II) fglrx(0): [drm] drmOpen failed (EE) fglrx(0): DRIScreenInit failed! (WW) fglrx(0): *********************************************** (WW) fglrx(0): * DRI initialization failed! * (WW) fglrx(0): * (maybe driver kernel module missing or bad) * (WW) fglrx(0): * 2D acceleraton available (MMIO) * (WW) fglrx(0): * no 3D acceleration available * (WW) fglrx(0): ********************************************* *
So I guess I need to find and install the DRI module? Is this just a simple matter of installing an RPM package or is it more complex than that?

If you are using nvidia drivers, you used to have to comment out the dri line in your xorg.conf file. I haven't installed the newer drivers, so maybe you don't have to do that anymore. But, you might check.
