[mythtv-users] False 'Error - No PIDS set' occurring

[ffrr]

I have occasionally noticed a .nuv file of zero length and, of course, 
it means I have missed recording a show. I have been trying to figure 
out why.  The log below shows what happened.  

The strange thing is that, I tried scheduling another show on the same 
channel (no restarts of either front or back end in between) and it 
worked fine.  One other, maybe, relevant data is that this was the first 
show it tried to record after a reboot of the computer.

Any ideas why it reported this, and missed the show.

from the log...
