Hi Bill,

Yes - you can run one tuner in ATSC mode and the other tuner in QAM mode 
(you connect an antenna to one tuner and cable to the other tuner).

In MythTV you set up two tuners for each HDHomeRun. In the ATSC + QAM 
configuration you have two sources and like the ATSC source to the tuner 
in ATSC mode and the QAM source to the tuner in QAM mode.
