XVideo performance degradation with 8178
I have an MSI 6200 card. When I upgraded to driver 8178, I noticed a signification performance degradation with XVideo. Mythtv playback of HD content stutters with 8178, where it was handled easily with 7676.
Also, enabling "sync to vblank" in nvidia-settings (which is the default) still hangs the system when using the XVideo system in 8178. I was hoping that would be fixed.
