This question comes up every now and then but I don't recall anyone
reporting that they actually tried it. I think it should be possible as
long as you don't have frequency overlap (i.e. you don't combine
channels on the same frequency but with different modulation).

Yes, at the driver level, but I don't know if myth would support this.
Actually, it seems like it might work but you will have to manually edit
the dtv_multiplex table and set the 'modulation' field appropriately.
You will also have to create the video source with the combined set of
channels by hand.
