The initial Live TV card is selected bottom up (and only with "Avoid
conflicts..." set). I have no idea what happens when you change
channels in Live TV to a channel that's not available on the source(s)
connected to inputs on this card. But based on some of the bug
reports/tickets we have had about changing to channels on other sources,
I'd guess that a) it's not actually working according to any grand plan,
right now, and b) all the previous attempts to allow users to change to
channels on other inputs without hitting NEXTCARD or NEXTINPUT (or using
the MENU) have muddied the waters so the behavior is probably far from
predictable, now.
I /think/ that when you change to a channel on another source, current
MythTV code will go through in your preferred-for-recordings order.
Therefore, if you want to control which cable-TV card/input is used,
you'll have to use the MENU|Source|Switch Input approach.
FWIW, my solution is to never use Live TV. ;) (Yeah, I realize that
not everyone can live with that approach.)
