Ok, no sooner do I post that firewire seems to be stable than I get
another failed recording.

Here's the backend log for the time the recording should have been happening:

Does anyone know what "Can't handle large PAT's" means?  I don't
recall seeing that with .21.

The effect of this was that no recording file existed on disk but
there was a stub recording in the list of recorded programs.
Attempting to play and then delete this recording results in:

2010-01-09 18:38:44.091 Preview Error: Run() file not local:
'/GetPlaybackURL/UNABLE/TO/FIND/LOCAL/FILE/ON/mythtered/3131_20100109173000.mpg'

2010-01-09 18:39:11.707 Reschedule requested for id 0.

'/GetPlaybackURL/UNABLE/TO/FIND/LOCAL/FILE/ON/mythtered/3131_20100109173000.mpg':
No such file or directory

It's odd that the "Can't handle large PAT's" happens near the end time
of the recording, but it never got so far as even opening a file for
it.

If I go into LiveTV and try to tune to the same channel, it comes
right up.  (Of course, I didn't try this until after the recording
should have ended.)
