Can the TV have a live S-Vid _and_ coax in at the same time? I would doubt
it.
Coax is for RF (Radio Frequency) and goes to the TV's tuner. S-Video is
already a video signal. The S-Video input is usually shared with one of
the composite video inputs (RCA jack). Your TV manual will tell you
which jack is shared.
If not, I can design a system that will let me use coax switches to put
the video tape to the TV _or_ the Hauppauge. But it requires coax into the
TV.
Why are you stuck on the coax thing? Are you saying that your VCR is
such a piece of shit that it doesn't have a composite video output?
Remember, I have 3 inputs on the TV and 4 peripherals to input ... unless
we drop the DVD player and play DVDs on xena.
Must think ... ouch, hurts!
I have come to the conclusion that you are clueless about signal paths.
I will attempt to do a little ASCII art for you to see if it helps. This
is best viewed with a mono-spaced font.

So now your question is, how do you watch the VCR on the TV? Simple: You
select it in MythTV as an input. So your VCR signal path is:
|VCR|------>|PVR-150|------>|TV|
The path from the VCR to the PVR-150 is also how you transfer your video
tapes to digital format, by recording them as an input.
BUT, if I don't split COX and send coax to the TV, how do I record one and
watch another? No, coax is the way to go.
For that part of it, yes. But not for the VCR. Use the composite out of
the VCR.
You don't need the converter. Just use a regular S-Video cable from the
video card to the TV. You will get a MUCH better picture. Not that the
dongle mixers are total pieces of crap or anything...
On the coax input to the Hauppauge, I put a left-right switch (I know
those degrade the signal, but maybe not too much). Right comes in from
Cox, left comes in from the videotape player.
Doesn't the VCR have a composite video output from an RCA jack? It
provides a much better signal path than having to go through the
modulator in a VCR.
Yes but see above. Are there S-Video switches/splitters? Flexibility is
more important to me than marginal improvements in signal to the TV.
BTW, the documents are all found (and the study is cleaner). The PVR-150
says it sent me a S-Vid -> Composite converter, but I don't remember it
and can't find it. It's not the sort of thing that would get discarded or
moved -- not around here.
If you can get composite video, then send that to the PVR-150 on its
composite video input jack.
Who's handling sound in all this? Also, what's the story with that little
wire that CD/DVD payers ship with that's supposed to go to pins on the
sound card? What's that all about?
Sound on xena goes IN to the PVR-150 through the little stero plug.
Sound comes OUT through the sound card. You will probably need a
mini-stereo plug to RCA Y-splitter and some RCA audio cables to hook up
the sound.
I'm going to leave for Fry's in about 10 minutes. Not to hurry you, but to
let you know your window.
Deeply grateful for the help and advice.
BTW, I seem to type faster than this Gyration keyboard can keep up with.
If you knew how fast I type, that would shock you.
I actually have extras of all these cables/connectors. If you would like
to borrow them first to test everything out before you buy them then let
me know before 1pm.
