John,
Thanks for the reply. I really appreciate it. I guess my last question
on this is: Does anyone know how I can get the Card Input ID (the
cardinputid column under the cardinput table) for the card that is
recording? I'd like to pass that value to the script so that I can run
ivtvctl -q 0 on the two Tuner inputs for my PVR-500. If I can get that,
I can modify your shell script that will do the rest. Thanks. I really
appreciate the help.
