Yes, two capture devices, where the ivtv one would issue an external channel
change command using 6200ch, and just keep an eye out in Upcoming Recordings
for collisions. I had aspirations of modifying the code, but in the end it
didn't turn out to be a big enough problem to motivate me to do so.

that shouldn't impact the QAM signal. Oh wait, I see you were switching to
cable, not FIOS. It was someone else who brought up FIOS.
I don't know. I never had non-HD cable. If I had to bet a dollar, I'd say
it's there, since the cable company probably would like to be able to simply
send a signal to your set top box to enable/disable services which are
already present on the cable, plus the must-carry rules. But I really don't
