Thank you for the good response bjm. So MythTV never uses the tuner
priority for Live-TV and instead just uses the highest number card to choose
the Live-TV tuner. I will give reordering the tuners a shot.
Furthermore I don't really understand how the card numbers are assigned.
Right now I have the following tuners: HD1, HD2, HD5, HD6, & cable7. Tuners
3 & 4 were deleted before adding tuners 5, 6 & 7. Yet when I exit
mythtv-setup it displays warnings about tuners 3 & 4 (i.e. Tuner 3 is set to
start on channel 2 which doesn't exist, do you want to fix this. . . etc).
