Here's the log.  Turns out the h.264 may be a red herring.

The log shows 2 movies:

G-Gorce.avi, which was recorded with h.264 and it works just fine.
naushika.avi, whch was also recorded with h.264, disables all keyboard
bindings, including volume, quit, everything.  If you allow it to play
to the end, it exits normally and the keyboard becomes functional again.

I'm attaching a log of the two play back situations with mythfrontend -v
playback.

Here's what mplayer -identify has to say about the two movies:
