[mythtv] truncated pvr-500 recording... "select timeout"

Hi.  I'm using r7386 and things are going mostly well (I have problems, but the
discussions on this list sum them up pretty well).  Tonight I got a truncated
recording off of one of my pvr-500 tuners, though.  Here's the relevant portion
of the backend log:

2005-10-07 18:59:52.370 TVRec(2) Error: HandleStateChange(): Null transition

select timeout

It looks like the backend knows the correct start and finish time, but the
recording stops at about 24 minutes in (instead of the 30 minutes it should
have recorded).

I don't know exactly when the select timeouts started, and they unfortunately
don't have timestamps on them, so I can't confirm if they started when the
recording died.  Sure seems suspicous though :)

My questions:

1) What is the "select timeout" signifying?
2) Is this a possible side effect of the other issues/open bugs right now?  I
know nobody's logged anything with "select timeout" in it, anyways.  Should I
just log a ticket?
3) Unfortunately this doesn't happen very often.  What backend verbosity should
I run with to catch it if it happens in the future?
