No, the priority scheme is not broken.  Your understanding of how the
scheduler uses it is broken.  When SchedMoveHigher is enabled, the
scheduler moves recordings around one at a time and the first fit
wins.  it does not continue on looking for "better" fits.
Consequently, recordings might get moved to lower priority inputs or
channels.

If you want to see how the scheduler arrives at its result, add "-v
schedule" to your mythbackend command line.  If you don't have any
off-line slaves, you can perform a dummy schedule by running
"mythbackend -v schedule --testsched".

If you never want the SD channels to be used, then you should mark
them as invisible.  That's what I do.
