We do have to stop calling ATSC/QAM tuner capture devices.  They
are demodulators of a digital signal rather than frame capturers.

However, what was your thinking on placing one or two NTSC capture/compressor
chips in the box, or in a variant of the box?   Then it would be able to
be all a user needs for Myth.    How much are those chips?

You could, in theory also do just plain capture without compression, since
HD people all have powerful CPUs, but that's not quite as good because
you get issues when people want to watch HD and compress 1 or 2 SD at the same
time.

Many might even find it satisfactory to have less than 4 tuners (ie. more tuners
than demod or capture/compress chips) if that made it cheaper.   Myth is now,
I think, supporting the idea that the same tuner can tune ATSC and NTSC because
it has two different decoder chips.
