[mythtv-users] Why does the log report 'No PIDS set, please correct your channel setup.' ?

[ffrr]

Even though this is a working system, sometimes it decides it can't 
record a show, or even show live TV.  The log has entries like...

TS mode).

Stopping and restarting the backend got it going again.   I don't 
understand.  It seems to be complaining about a misconfiguration, but, 
if that was correct, just restarting the backend wouldn't fix it.

Please help, it's getting annoying that myth is unreliable.  I can't 
trust it to capture my shows for me.
