I thought I'd dig out my old Via Epia SP13000 mini-ITX board as a spare
frontend for guests etc. It was retired about 3 months ago having run
really well for 4 years. With 0.22 loaded, I get very very slow video & TV
playback - something like 3-4 frames in a burst and then nothing for 2
seconds, then another 3-4 frames.

This is a typical log from the 0.22 frontend.

Comparing that to an old log I found from 0.21

I'm seeing the following error in Xorg.0.log
(EE) CHROME(0): [XvMC] ViaXvMCCreateSurface: Too many surfaces !

which makes me think that its a 0.22 specific problem as I'm running the
904 openchrome driver, the same as on 0.21 but I have updated the kernel
from 2.6.25 to 2.6.30 (the versions in between seem to have DRI driver
problems with openchrome). One other oddity - I can't seem to get it to
run realtime.
