Nice, in the sense that any time a card puts two functions on it that
you want it's nice, but these are otherwise pretty unrelated functions.
What they share is the RF tuner. The MPEG2 encoder would be only
for the NTSC.
The reason you would not want this is that if you get ATSC, you are only
likely to want NTSC from cable/satellite, in which case you would not
be using the tuner anyway.
The ATSC tuning process doesn't really involve the traditional A to D
used in a capture card.
So what would be nice would be a card which is a combo of the pchdtv
and a wintv-150.
Though another argument is that those who are not splitting their frontend
and backend will only put an HD card in a machine that can display HD,
ie. a fast one. In that case, software encoding of raw capture isn't
that much of a burden on the machine -- though capturing NTSC and encoding
it and playing HDTV at the same time might be a burden.
