Current MythTV still needs some work on the recording side to support
the HDHR 4k.  While it can tune by virtual channel number, it still
pre-allocates a tuner, now from a pool instead of a fixed tuner like
before.  However, unless SD has updated their API, I don't believe
there is a way for MythTV to request a tuner from the "right" pool.
The result being that MythTV could sometimes be given an ATSC 1 tuner
when it needs an ATSC 3 (or vice versa) one and cause the current (or
a future) recording to fail.
