So -- I disable XvMC, and everything works fine. I don't know if XvMC
takes too much memory (more than my 512mb). I tried enabling swap via a
network block device -- but it doesn't seem to matter. Regular playback
I also moved from my GeForce 5200 to the GeForce4 Ti 4600 with the HDMI
out (and a HDMI to DVI converter thingie). I still couldn't get
resolutions more than 1024x768 though.
So -- When my 2Gb gets here, I'll try with XvMC again (sometimes live HD
is choppy) -- I'll keep ya posted.
