That was probably me.

Sweet, nice to know I helped. These lines in rc.local should do it...
( dtvsignal and mythbackend have to be in the $PATH )

dtchannel=<put a good freqid here>
dtvsignal /dev/dtv $dtchannel > /dev/null 2>&1 &
pid=$!
sleep 2
kill $pid

I have myth set to use /dev/dtv.... to each his own

I actually don't have a second tuner... so I can't help you there. I
have an equally odd problem with my mythTV pcHDTV setup. Live TV works
great. All the channels and sub-channels are perfect. However, when I
try to record anything it records the wrong channel! Could be
