I too have a GT 430 and remember going through something similar. I
monkeyed with all the xorg.conf settings but in the end I think it
was a matter of making sure I had a recent Nvidia driver installed,
making sure /var/log/xorg.log showed VDPAU being loaded and, most
importantly, that VDPAU was selected in Myth's video playback
profile.<br>

I also see those VDPAU lines in my Xorg.0.log file (see link above). I have tried all three VDPAU pre-programmed options in the playback menu and futzed around with the internal VDPAU filters, # of cpu cores, and deinterlacer options but haven't seen a marked difference in playback.</div><div><br></div><div>My Xorg.0.log</div><div>[ 14.472] (II) NVIDIA(0): [DRI2] Setup complete<br>[ 14.472] (II) NVIDIA(0): [DRI2] VDPAU driver: NVidia<br><br></div><div><br></div><div class="gmail_extra"><br></div></div>
