Ha! I didn't realize that /proc/kmsg was mirrored as /var/log/kern.log. and
with human readable timestamps, even.
Unfortunately, it goes right from April 8 to April 10, so it looks like
whatever the problem was on April 9, it wasn't anything kernel/driver
related, or at least not something that the kernel or driver thought was
worth logging.

I have OTA ATSC via three PCI FusionHDTV cards, all connected via a powered
splitter/amplifier to the antenna.
If I'm reading the backend log correctly, that same card (#2) successfully
recorded 2 other shows earlier that day, on different channels. When I
tried tuning to the failed recording's channel the day after, that worked
too.
If it *was* a bad reception at the time, or a driver bug or something, is
there any way to tell myth to try harder, or try again?
