Another issue seemingly related to the QAM problem...

I have my PBS-HD station set up for both my QAM tuner and my firewire
tuner, for some reason the scheduler doesn't notice that the QAM tuner
has the channel, i looked at the channel table in mysql and except for
the tuning parameters both stations have the same information (name,
channel number, etc).

any idea why this would happen? I'd like it to record via my QAM tuner
to leave my firewire tuner available for other things.
