I'm in the US as well (I get New York OTA broadcast channels).  I
recently went from an old GeForce 7100GS with no VDPAU at all to a
small form factor GT 430 card and it handles VDPAU high quality
without a hitch.  Not only 720p/1080i OTA but 1080p x264 videos and
others as well.  That makes me wonder if it isn't just something in
your configuration.

I see you're getting audio buffer underruns.  It's probably one of the
first things you checked, but do you have Enable Extra Audio Buffering
set?
