yes, it ought to. i brought it up years ago. But have solved it for my situation by disabling channels on the 1st priority tuner.
It gets trickier, though, with the ATSC 3.0 request that OP brought up... especially if that HDHR has both 1.0 and 3.0 tuners. The passes that he wants to record in ATSC 3.0 would have to be altered to record only on 3.0 channels. And the 3.0 tuner moved to the bottom priority, like @Edwin_Perez mentioned.
