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). _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
