Ideally, upon attempting to tune a firewire channel and receiving no signal,
mythTV would dynamically fail over to another tuner in real time.

We discussed this on this list some months back.  This approach has the
significant down side that it means that new channels won't be added without
manual intervention.  I don't really like that.

I didn't know that.  So, are you saying that this is a Schedules
Direct problem?  They're saying History/HI is on freqid 127/128, but
it's not, and that's the ultimate source of the problem?

I have an HDHR Prime on pre-order.  I'm hoping that after it arrives,
I can script something that can get a proper channel map for all of
the tuners and make everything "just work" despite frequent changes by
the provider.
