the pins were the first thing I checked

yep, that's always been in my xorg.conf

just 640x480

I'm going to swap out the cable. The first thing I thought of when the
B&W popped up was that since the MX4000 works and the FX5200 doesn't,
maybe the S-Video out voltage level is flaky and maybe at the edge.
Since I'm running a long cable (10ft of S-Video going to a
S-Video<->Composite converter and about 20ft of RG6) that maybe it's
just not making it somehow. I realize that this is no where near the
length limit, but what the heck.
