Well I hope I've sent this mail to the right adress this time:


I dont know if it's relevant for your chip revision. I'm using the
Unichrome IGP inthe K8M800 chipset. HW accelerated playback through xxmc
(xvmc with usage of the VLD decoder) and xine worked but produced almost
more CPU load than Xv. Currently I'm using the unichrome save cpu option
(IMO this makes xine sleep waiting on the output of VLD decoder ). But
if you do so you have to make shure your kernel runs with a frequency of
1000 khz, otherwise you (at least I did) get stuttering video.

But maybe you know all this already.

Can you attach your "xine -verbose=1 ...." log ?
