It stinks that there's no way to know when a lineup change is about to come
and screw up the recordings.  I asked SchedulesDirect if they could notify
me when a lineup change occurs, but they cannot at this time.

I've not been checking the exit status of "mythchanger" with the 4250HDC,
so MythTV just records blindly.  I've just added logic to my channel-change
script to log if it exits with non-zero and "exit 1", but I'm not sure
mythchanger can detect failed channel changes.  I'm looking forward to
trying 0.25's internal firewire channel changer with the HD-PVR and see if
it's any better with error conditions.
