Unfortunately, if you wish to use the MPEG-2 decoder in the PVR-350, it is
that convoluted. Of course, the TV I had at that time had separate
S-Video and audio connectors, so I never had a problem connecting things
properly. (But again, remember, I'm in North America, where SCART is only
on imported devices.)
As somebody else mentioned in this thread, you can use the Xv driver for
the PVR-350 and bypass the MPEG-2 decoder - then you wouldn't have to have
the loop from the PVR-350 to your sound card, as everything would come out
of the sound card. However, that increases CPU utilization by a fair
amount, it really depends on how beefy a system you have.
However, to the SCART thing, because your TV doesn't support separate
audio in, you need to have some sort of cable that allows both devices to
be plugged into that SCART connector. Or, you could buy a separate audio
receiver, as you mentioned you were thinking about.
