So it sounds like the easiest, cheapest, and best thing to do is the following:

I'm running sound from the headphone port to my amp's A/V-2 (AUX) input. Full
stereo. Sounds great. But the video is running through the RF Modulator. So
it sounds like I should keep the sound the way it is (stereo) and have a cable
made that runs RGB off the Genny and into an RCA video jack (like the one
running from my VCR).

So the question is, does the genny sense that you're using the special port on
the back and cut the headphone output? I assume not.

Also, supposing I've only got one video input to the Monitor/Receiver and
that's used by the VCR. Can I put a splitter on there with no ill effects?

I just want to maximize my capabilities (i.e. stereo is a must). But when I
read the original instructions it seemed to me that if I wanted to use the
special cable, I gotta bag stereo. I want BOTH - best picture and best sound.
Can I use two cables (one from headphone out to stereo amp, and one from the
special port on the console to Monitor/Receiver Video-In (RCA))?

What's the big benefit? Genny looks pretty damn good now (through the RF box).
