Hello,
Switch off composing is not needed on latest drivers (it was bug, but it is fixed)
Except this I have similar problem, independent to composite desktop on or off.
CPU usage from xine is between 5%-50% and it drop video frames.
All libs (ffmpeg, x264, xine-lib-1.2-vdpau, xineliboutput) are from yesterday repositories, driver is latest beta (195.30)

Have you switched off compositing in the xorg ? Depending on your CPU -
this is to high CPU usage still. I have below 10% at HD and around 5% or
lower for SD while watching TV. Also denoise/sharpen of vdpau on SD
content provides quite good quality picture even on SD.

If you are fine with xv - but see above - the only time i came in that
range IMHO was back at the days where i still used my Turion ML-30 at
some of the HD stations (not all).
