As far as tuner priority, that's used for determining which tuner to use.
Or at least that's one of the uses. So if I set up a rule to tape CSI:Miami
whenever it's on and whatever channel, I'd prefer it tape it off one of the
HD channels and not the analog, if the same episode is playing both places.
So I give the firewire a higher priority than the analog tuner. Works well
Back to the channel table fields, I have my QAM channels all setup and
working now, except for one. For some reason, what should be my HD ABC
channel is actually displaying the ABC DT subchannel that runs news 24/7.
The original scan found 3 ABC DT subchannels. I tried using phpmyadmin to
change the service ID for that channel to that of the other two subchannels,
but it had no effect.
A couple of possibilities occur to me. First, mythbackend caches all the
channel tuning info when it starts up and because I didn't restart it my
changes to mythconverg had no effect. Second, I'm changing the wrong thing
or otherwise still am confused about the cause and effect going on.
