After the stuttering occurred, I skipped back, and replayed the segment again. Now, the video skips over the affected area (1-2 sec skip). This is also output by the mythfrontend:<br>

</div></div>Is the problem with the recording, or the playback? Try moving<br>
backwards in the LiveTV recording past the point where the problem<br>
happened, then let it play the affected bit again and see if the<br>
problem is still there.<br>
