DVI to Component Out Adapter doesn't work

The darn ATI DVI -> Component Out adapter [see post] I bought does nothing.

I set my resolution to 800x600, then went to Advanced, Adapter Tab, "See All Modes," set 640x480, 32bit color, 60MHz (didn't see 30MHz for interlaced TV), and shut Pharra, my PureXS [blogs|shrine], down. I turned on the Sharp 32" TV, rebooted, and nothing. The TV never got a signal.

Perhaps X1900 XT's can't do this. Perhaps I should turn off Crossfire... but not, it should have gotten a signal at least.

Bleh. $25 for the adapter and $20 for the (far too short) component cable). And here all I wanted to do was run MAME.
