Just an update....

Splitting via a Y-Connector the Composite 990 Output did not result in any (noticable) degradation of video...even on a large screen projection display.

Not sure why that would be, since the p-p output on the 990 is listed at 1.0v. vs. a higher 1.5v. on the older 950.

I realize that splitting an SVIDEO output would be an absolute "no" .... but it seems that composite signals can tolerate alot more. Running the composite output to a switcher would still involve additional connectors and cables, so that it would seem that a simple y-splitter is not likely to be any worse.
