[mythtv-users] "The file for this recording is empty"

Sun Oct 19 19:08:22 UTC 2008

I recently started getting an error "The file for this recording is empty"
when I tried to watch a recorded program.  I'm running Mythbuntu on an AMD
Athlon XP 2500 with 1.5 GB ram.  I'm capturing video on a Hauppauge
HVR-1600.  I had to recompile my the Hauppauge driver recently when the
kernel was updated.  I recorded a few shows successfully after recompiling,
so I don't believe driver is a problem.

I pasted a good portion of my mythbackend.log file.  I've seen some
suggestions not to paste too much, but I'm not sure what is important and
what is not.  I apologize if it is a bit long but I didn't want to omit
something the I thought looked benign and was a key piece of info.

I also noticed that it seems like things start working again if I reboot in
the morning.  It appears like this could be related to the timing of running
mythfilldatabase at around 6:00 am.  It seems like I'm good up until that
point and then I need to reboot after.

I appreciate any help you can give.

Thanks,
Greg
