Yes indeed. At least here in Australia where all the Myth people I know just
record FTA digital channels, all tuner cards are essentially equal as far.

I've never understood why MythTV schedules the input card along with the
show to be recorded. Why not just schedule the recording ahead of time, and
then pick the best available input "live", i.e. when the recording is about
to start?

If no input is available to record How We Built Apollo 11 because the better
half just tuned into Biggest Loser live, then perhaps a pop-up can give the
user the option of which to persevere with.

It should still be possible to predict scheduling clashes, based on the
assumption that no-one is watching live TV.

[Sorry for getting in rather late on this thread, but this issue is rather a
pet-hate for me about otherwise-fantastic MythTV]
