MacBookPro DVI output problem

[zullf]

I purchased MBP to use it, among other things, for VJing. A lot of great VJ software is available for both OS X and Windows platform and i use it both.
I purchased DVI to S-video adapter and connected MBP with projector and it worked perfectly well.. Then I switched to Windows and tried to get the same thing but I couldn't get anything on projector. I guessed that it could be something wrong with adapter so I tried to connect regular monitor directly to MBP DVI out and it didn't work as well... Got back to OS X and it worked perfectly.
Under windows, when i plug DVI adapter to DVI out, it recognize "something" and it allows me to add secondary display in graphic card settings but doesn't output anything. I tried to replace original ATI drivers with Omega alternative but that doesn't make any difference...

Anybody had similar problems? Is this driver/compatibility problem or it's just my MBP?
Any solutions?
Thanx!

Under Bootcamp? If so it is still a beta and all features might not work. Try it through Parallels virtualization (free to try).

I have a first gen MBP 1.83ghz with boot camp installed. At first i had no luck with using an external monitor while in bootcamp. after doing some searching on the net, i got it to work. Basically you have to fudge around with the ati catalyist tools a bit and it will work. This was months ago so i don't remember the specifics but, i know i got it to work. This was also with the original version of bootcamp, so i would think with newer releases it should be easier to accomplish

Might also try reducing the refresh rate of the adapter under Windows. Just a guess.
