video lock-up every few recordings; at my wits end :(

I *think* this may be ivtv-related, but I've got no feedback as yet
on that mailing list, so I thought I'd try here in case anyone's got any
ideas, because I'm pretty well fresh out.
My Myth box [FC3/0.17/ivtv-0.2/ATrpms] is *this* close to being
finished, but I'm stuck with a semi-frequent (every day or two) lock-up
that means I can never guarantee I'll get a recording OK :(
Every so often, a recording generates zero bytes, and Myth becomes
deeply unhappy about this (it doesn't seem to realise, it just plays up:
backend refuses to access the tuner agani, frontent crashes upon
accessing the file). I have to reboot, *then* stop & restart the
backend after it's come back up to get it to work again.
Once it's locked (prior to reboot), I see a zero byte 'ongoing'
recording; I can kill the backend and do 'mplayer /dev/video0' (this is
s-video only) and get no output (ditto 'cat /dev/video0 > test.mpeg' ==
zero length output).
It *seems* to happen at the very start of recording; it *may* happen
only straight after another recording (or even only at the *end* of
recording) as I think I've only got it [so far] in between two
concurrent progs.
In between, it can work (record/playback/watch-tv) flawlessly. I
have also had a no. of 'back-to-back' recordings work OK, so it's not
specifically that.
I've tried pre-emptively rebooting every night, turning off comm.
flagging, double-checking Live-TV works beforehand, and nothing seems to
make a difference. I just can't see the common factor that causes it to
go wrong.
I have mythbackend logging verbose output, but at the transition of
end-of-OK recording to null-recordnig, I can't see anything out of the
ordinary (does the backend *really* continually check all recordings for
comm-flag processing that frequently?).
FWIW, my verbose ivtv logging can be found at
http://www.fnxweb.com/data/ivtv.log - this /does/ seem to indicate at
least the /acknowledgement/ of something being not quite right, but I
don't actually understand most of what it's telling me (there's logging
from just before to just after the start of a duff recording that
'started' at 22:00).
