<div>XvMC and HD are working ok on my system, but I'm still having issues with occasional hiccups where the video pixelates slightly and the sound skips - probably several times per minute. I predominately get two type of error:
</div>
<div> </div>
<div>ac-tex damaged</div>
<div>and</div>
<div>invalid mb type in [B,P] frame at ....</div>
<div> </div>
<div>I dound this thread referring to ac-tex but I think it might be a different issue:</div>

<div>Possibly related are some issues I had with two recent HD recordings. They played back fine to a point, then froze and started eatting memory until the machine killed myth. They will both consistetly do this at the exact same point, respectively, in playback. If I can get past that point, by skipping forward over it, the playback continues along, but completely without sound.

<div>One final issue, though likely unrelated, is that the entire machine sometimes freezes when changing HD channels. Again, don't know if it's related.</div>
