[mythtv-users] Recordings get reset at 4:40am

[Justin Alcorn]

I record Rachel maddow every night, and occasionally it gets pushed to the
4am showing.  Whenever it does that, my recording is only 19 minutes long.
The first 40 minutes are lost. This has definitely happened the last 2
times it recorded at 4am, which doesn't happen very often.

It appears that /dev/video becomes unavailable. (It's an HDPVR)

I've been looking at cron jobs that run at that time. The find on
.mnt/disk/share doesn't affect the mythtv recordings library - and it runs
every 2 minutes 24/7. I don't THINK the php5 session cleaner should have
anything to do with recording. lastsnap just creates a symlink to a image
file (the last snapshot taken by motion). speedtest runs every 10 minutes
24/7 and runs a speed test and graphs it.  It affects network, not video or
disk.

That leaves checkmotion.sh, which makes sure motion hasn't crashed and
restarts it if it does.  I could see that affecting /dev/video0, but I'd
get an email if it did the restart, and no email was sent.  Also, it runs
often

I thought it might be mythbareupdate.py, but that seems to run 1 minute
later than the problem I'm having, so...coincidence?

Is there some job that mythtv is running that is closing the /dev/video0 ?
Any ideas of other places to look?
