I have a 6600gt, version 8178 of NVidia's drivers and the following 
setup for VDR and Xine:

/vdr/setup.conf:
xine.autoPrimaryDeviceMode = autoPrimaryDeviceOn
xine.modeLiveTV.prebufferFrames = 8
xine.muteMode = muteSimulate
xine.osdGammaCorrection = 123
xine.osdMode = osdBlendClipped
xine.transparencyMode = transparencyOn
xine.volumeMode = volumeChange

~/.xine/config
audio.driver:esd
audio.device.alsa_front_device:default
audio.volume.remember_volume:1
video.driver:xxmc
video.device.xvmc_bob_deinterlacing:1
video.device.xvmc_more_frames:1
video.device.xvmc_nvidia_color_fix:1
video.output.xv_deinterlace_method:none
engine.performance.memcpy_method:mmxext

With that I get about 50 - 60% load with AMD XP 2800+ when watching 
EURO1080 via cable and OSD works also. My understanding is that you 
cannot use postprocess deinterlacers with xvmc, but I am not totally 
sure about that.

PS This config isn't used too often so it is most likely the  best possible.
