There is nothing inherently wrong with having a PVR and a "software"
tuner in the same system. I used an HD-3000 and a PVR-350 together
and it worked fine, but I was using the V4L drivers for the HD-3K.
You want to make sure that you have the recording profiles for the SW
tuner set to something sane, if you are low on horsepower don't try
MPEG-4, use rTJpeg.
If you can watch live TV with a card then you can record it, because
that's what you are watching in LiveTV - a recording. You might want
to check your "default" recording profile because that's what will be
used for a recording.
Also have a look at your logs, might give you a clue as to what's
happening.
