While it is possible that something just happened to the hardware, the 
reason I suspect this is not the case is that everything worked 
perfectly for 4+ years and then I had a 2 drive failure on my RAID 5 
recording array.  So rather than rebuilding with CentOS 5, I went with 
CentOS 6.  Now the problem occurs after 2-3 days to both PVR-150s nearly 
simultaneously.  I suspect if I were willing to accept the downtime, I 
could rebuild the system with CentOS 5 and everything would just work.

Now, I had thought of making a script that detected a failed recording 
and reboot the machine.  But your suggestion is obviously much better as 
if I create a script to wait until mythbackend isn't going to record 
anything in the next 10 minutes, then reboot.  Then set the script to 
run every night, it is a reasonable work around.  I'm not sure where the 
problem is to know who to open a bug against.  Any pointers to 
troubleshooting this type of problem?  I'd rather get whatever the issue 
is fixed in CentOS 6 rather than rolling back to CentOS 5 one weekend 
when I can afford some downtime.
