If you increase the priority of the HDPVR tuner, that should do what
you want:

If you give it a big number (say 100), that will overwhelm other
sources of priority and make it the tuner of choice.  Then you can
give the HD channels a priority boost also (from the channel editor),
to make them preferred over the SD ones.  Be aware that this can make
MythTV wait for a later HD recording and bypass recording on an SD
channel in favour of the later HD one.  Which is good if the HD
recording succeeds, but bad if it fails.
