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 
works though.

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.
