Jumping in late in the thread. I wrote a little script which allowed me 
to poke good values into the mythconverg database when the backend got 
stuck tuning a bad channel.

This has been rendered safe by commenting the last three lines.
I called it good-channel-poke. Takes 2 inputs: Channel and card.


echo "Args provided: Channel: "   $Channel "    Card: "     $Card

if [ $1 = abc ];
   echo "You must provide a channel number."
if [ $2 = xyz ];
   echo "Need to give a Card number."

#echo 'update cardinput set startchan = '$1' where cardinputid = '$2' > 
#mysql -u mythtv -pmythtv mythconverg < /var/tmp/startchanfix
#rm -f /var/tmp/startchanfix

         Please let me know if anything I say offends you.
          I may wish to offend you again in the future.
