With CVS from last night, I now cannot use XvMC at all. It stutters ALL 
the time, and is totally unwatchable. Previously (CVS from a couple of 
weeks ago) I could watch it, but OSD flickered, and I got a few stutters 
here and there usually with a 'prebuffer pause' on the console, but it 
was usable. I still went back to plain xv since it worked fine. xv still 
works fine with the new build (it actually seems better, I only have 
about 25% CPU usage now) but it would be nice to have XvMC available. I 
am using nVidia GF4-MX440 with 6629 drivers, on an AMD Sempron 2200+ 
board (VIA chipset). And yes, I did disable libmpeg2. This is all with 
SD-TV btw.

I have not tried upping the logging yet, if anyone is interested I can 
certainly do that tonight.
