Thanks for stating that so clearly. It's not what I wanted to hear,
though. :-)

The trouble is, it would need to be a triple-split cable, with
audio out from the PVR-350 to the sound card, then audio out from the
sound card to a SCART connector, plus video out from the PVR-350 also
to the same SCART connector.

So, then I'd get something like this:

      |          |
      |    TV    |
      |          |
         /  \
      1 /    \_
      _/     |\
      /|       \
     /    /|    | 
     \   / | 2  |  3
      \ /  |    |
       |  \|/   |
     |           |
     |     PC    |
     |           |

where 1 is Video Out from the PVR-350 to a SCART that plugs into the TV,
2 is Audio Out from the PVR-350 to the PC's sound card, and 3 feeds back
from the sound card to the SCART connector going into the TV to bring
the sound full circle.

Does it really have to be this convoluted? Can such a cable even be
made, with split audio and video out, plus an audio in, which must
terminate in a SCART connector, along with the video out?

I can't help but think that there must be an easier way. How do other
PVR xxx owners get music and other system audio?

SCART seemed like an improvement when it first came out, and I suppose
it was, but since then, I've had a lot of trouble with it, since so many
cables and devices don't use all of the pins in the same way.

Thanks again for your help.
