Baffled by XvMC on nvidia.

I've been trying in vain now for several days to get XvMC working on my myth box.

To simplify matters i've been testing with mplayer using:
mplayer -vo xvmc -vc ffmpeg12mc test.mp2

but it always gets stuck playing at the same place:
I get a burst of sound and a black video window requring me to ^c out of it.

I was trying this xvmc stuff out of curiosity a few weeks ago when I was reading a xvmc thread in nvnews forum. It works with compiz running.

I was able to play some sample files with no error, following is one of the output:

Interesting. I managed to get it working eventually but only with drivers 100.XX 96.XX & 71.XX

gives me a 30% drop in CPU usage vs xv.

169.XX & 173.XX break as described above.

I haven't tried 177.XX but don't hold out much hope!

Interesting that you both have 6600GTs.
Junksui is yours AGP or PCI-X?

My 6600GT is pci express.

I have a 6200 agp and I am right back on 96.43.07 as I thought some patches from:

https://bugs.gentoo.org/show_bug.cgi?id=218178

were needed on 2.6.25+ kernels

XvMC runs fine on the above driver which i think is 96.43.05 with a patch
