Trying VDPU with an 8400GS 512MB Card with your 0.21 builds.

I've been testing HD broadcasts with HE-AACV2 audio (nz freeview|HD)  
and I'm seeing the same audio errors. It starts with the video  
dropping behind the audio errors and then the NVP messages appear and  
the audio starts to stutter.

I've checked my configuration and I have your recommended options.

I'm not seeing the issue with MPEG2 material and MP2 audio.

Any other ideas.
