MacBook Pro DVI-Out and FrontRow Color Anomalies

Question

ok, so i've got one of the first generation MacBook Pros 2.0GHz processor, 2GB RAM, etc. i want to use the DVI-out to connect to my Sharp Notevision projector, which has a DVI-input. i have a standard DVI cable and when i connect, everything is fine. i can display at the projector's 1280x1024 native resolution and finder and other application windows look just fine, color-wise.
however, when i jump into FrontRow (or play any Quicktime movie or use iTunes to play movies), the color shifts and looks horrible. the glow around the icons in FrontRow are oddly red, and other nuetral colors look greenish or otherwise. its almost like you've got a component cable connected with two of the channels swapped.
the same projector works fine and displays accurate color with my AppleTV and if i connect the laptop to one of my Cinema Displays, the colors for movies are all accurate. i thought maybe the DVI cable was bad, and bought a replacement and the new cable produces the same off-color results.
any help or guidance here would be greatly appreciated!
thanks,
scott

Another update, I did some research and it seems that ATI are cagily admitting to the fact that there might be a problem with the X-series;

You'll notice that ATI tell you to contact the manufacturer of your computer if the graphics are integrated into the motherboard. Like with Apple. Much joy to be had there.
I phoned their technical support and got talking with a specialist who was mystified and suggested 'turning off the airport'.
Also, it seems that Apple rather significantly "underclocked" the GPUs in their macbook pros;

Could be running the GPUs are running on a lower voltage and maybe they're not working right, or the signal isn't stable enough to pick up an EDID? It seems to be quite a mystery. Perhaps the osx86 community will have some tricks up their sleaves for twisting the x1600's arm. Still doesn't explain why the monitor worked that one time.
This probably isn't an issue for anyone who doesn't want to plug their laptop into an external display, but I suspect it's a widespread problem just waiting to rear its ugly head, especially as HDTVs become more ubiquitous.
Anyone else struggling with external display devices, or with solutions, I'd appreciate your input.
