Fixed!

Steve at Outlaw ran out of suggestions and was about to recommend sending me a replacement, and an RMA for my unit. However, both of us thought it wierd that all of analog audio, composite video, and svideo would not appear, as they're handled by different boards. I wanted to make doubly sure before having Outlaw go to all the trouble to ship another unit out. Steve suggested, (paraphrasing), "You know, you could try resetting the unit."

Sure enough, I followed his instructions and Video 1 Rec / Out is now active! Thanks, Steve!!

The only remaining problem is that svideo on the Video 1 Rec / Out is black and white from the only connected source (well, the DVD player is connected as well as the cable STB, but it's configured for progressive scan output on the component lines and that is documented to mess up the svideo output). However, I attribute that to broken chroma connections on the fragile svideo cable. I'll verify that, of course, but am confident that the problem is not with the 990.

BTW, Outlaw support is quick and friendly. Kudos. Steve emailed that he would try to repro my problem on Saturday, but I emailed back that he should try to enjoy the long weekend and not work on my account -- it could wait until Tuesday. Definately above and beyond the call of duty. It's nice to see that kind of dedication and comforting if I had a real problem that couldn't wait.
