<div style="direction: ltr;">Is it typical to have varying audio <span id="st" name="st" class="st">sync</span> on HDTV? Roughly
50% of the shows I record are <span id="st" name="st" class="st">sync</span>'d correctly. Another 40%
typically have the video 80-100mS ahead of the audio. Ten percent
of the time, the audio is up to 800ms off. I have to adjust the audio manually from the menu during playback but
that has to be reset after every fast forward or commercial skip so it
is pretty annoying.<br>
<br>
Tried these configurtations:<br>
Alsa:spdif, Alsa:default, or /dev/dsp<br>
AC3 passthrough on or off<br>
Use video as timebase on or off<br>
<br>
Base system:<br>
MythTv from SVN from couple of days ago<br>
Pentium 3.2 w/ht, plenty of cpu available<br>
Fusion Gold 5 HDTV cards<br>
Ubuntu<br>
Vanilla Kernel 2.6.15<br>
Using realtime priority.<br>

Here is <span id="st" name="st" class="st">a</span> copy of my log when switching to watching TV. Nothing
seems to jump out as <span id="st" name="st" class="st">a</span> problem but hopefully someone that knows more
about mythtv than I do, can pick some clues out of it.<br>
