The mythburn.log file can be seen at
http://www.bostongeeks.com/tmp/mythburn.log

There seems to be other lines that may be problematic before the end
(you can see those in the logfile linked to above), but at the end of
ffmpeg I get:

This is under Fedora Core 6, Athlon XP 2400+, one PVR-350.  It looks
like all my myth stuff was updated via yum Saturday 04/28/07:

Googling for that error message only turns up errors from several years
ago, so I doubt they're still relevant.  It smells like an
incompatibility caused by the upgrade.  I tried this with several
different input files, so I don't think it's the input files.

Any ideas?  Thanks.
