Well, I'm told off list by somewhat respectable people that Mac OS X no
longer has the problems handling multiple simultaneous media streams
that one may have feared being a problem.
I do strongly recommend finding a way to try your setup out before
actually sinking the money into it. In particular, you mention a dual
1.4ghz G4 and a G5, and I've heard a lot of reports of those two
machines being quite noisy, but they may not actually be so bad in your
sanctuary and with your processing load (keep in mind that a G5 varies
it's fan speeds as the heat output, i.e. load, vary).
Are you sure your G4 800 can't do the task?

Have you looked at stand alone DVD recorders? You mention $500 for
getting video into the computer, but there are now stand alone DVD
recorders that cost less than $500.
If it were me, getting the video capture out of the computer while
trying to do the other things would make me far happier, even if
reliable people say it can be done. But then, for somewhat important
things (say things that would be painfull or embarassing if they fail),
I tend to be a one task, one device kinda guy.

There used to be a lot of decent cheap Svideo in cards for Macs.
However, none of the ones I had any familiarity with at all were
supported on OS X. I know that there are still cards that support
s-video in on the Mac under OS X. I just don't know what is cheap and
what is good. The reviews I've seen of sub $500 s-video -> DV
converters have tended to be fairly good.

Would it be possible to use a console extender and put something
non-rack mounted in the amp closet?
