</div>Sure, just like there are lots of problems with preview images in<br>
MythWeb on 0.21, and lots of problems with incorrect video scaling on<br>
0.21, and lots of problems with Myth's finding recordings on 0.21, and<br>
lots of problems with starting Myth on 0.21, and lots of problems with<br>
tuning channels on 0.21, and lots of problems with getting audio on<br>
0.21, and lots of problems with playback on 0.21.***<br>
<br>
***When users misconfigure PHP timezone, DisplaySize, Storage Groups,<br>
HOME environment variable, video sources/input connections/channels,<br>
sound card, playback profile groups, respectively. In other words,<br>
people who haven't yet configured MythTV 0.21 properly have performance<br>
problems with HD on 0.21. Specifically, you need to configure the<br>
playback profiles appropriately. See<br>

<br>Turning XvMC on, leans to the same studdering when the OSD is up. For now I am going to have to just deal with this. I wonder if this is a Myth issue or a driver issue.<br><br>Mitchell<br></div></div><br>
