Input priorities ("tuner" priorities) are evil--they tell MythTV what to
record, not where to record it, so they don't do what people expect they
do. Also, priority /never/ has any effect on capture card/input chosen
for Live TV.
Therefore, you probably shouldn't be using input priorities. (Please
read all of http://www.mythtv.org/docs/mythtv-HOWTO-12.html for details
on how priorities work.)
Instead, "Delete all capture cards" (won't affect channels--but will
reset everything so you can configure it correctly and without input
priorities), then re-create capture cards and re-connect inputs.
Create capture cards in the opposite order you want them used for Live
TV and make sure you keep "Avoid conflicts..." enabled. (So, sounds
like you want to create the DVB-S2 cards first, then DVB-T cards.)
/Then/ connect inputs in the order you want them used for recordings.
And note that the capture card order need not be the same as the input
And don't ever set any input priorities, again.
