One input. I'm assuming you could have an 8-vsb channel on 21, and a
QAM-256 channel on 120, so if you had digital cable that used only
channels above 83, you could combine an antenna and cable inputs with
a lowpass and highpass filter, resp. The modulation of each channel
is specified in the dtv_multiplex table so each channel can have it's
own modulation within the same source.
So each tuner has it's own physical input? (i.e. unlike a PVR-500)
Can they issue DiSEqC commands?
