Previously in shadows and dark scenes there is a colour cast which varies from recording to recording in it's colour and severity, the display (a DLP projector) is calibrated to reduce this but it varies so still shows up some of the time. Set display mode to YUV and immediately shadows are as they should be, detail in shadows is clear and the correct colour :-))

Yes, it was your port of vdpau with studio levels (thanks) that got me to ditch the PS3 for playback and start using a Myth frontend, prior to that I always got poor image quality even with plenty of cpu available.

The point I was making is this gives a subtly better result than previous versions.
