You've got ugly H.264 recordings encoded with settings that MythTV (or, 
more likely, its version of ffmpeg/libav*) isn't designed to work well 
with, and MythTV is telling you about it.

Likely if you upgrade to current 0.24-fixes, you won't see the log spew 
(and MythTV will work much better, overall, especially with "cutting 
edge" CODECs, like H.264).
