DirectX 9 causes black screen

[archangel2005]

I have a fresh install of windows 2000 with service pack 4. don't laugh, i bought it and for now am gonna use it till they pry the windows 2k disk from my cold dead fingers, but, heres the thing, fresh install with video and sound drivers only, i load vlc, and the movies play fine. i install directX 9 and the video is dark. attempting to change the player setings doesn't help.
am i missing a file maybe that corrects this problem? i have other windows 2000 computers with fdirectx 9 and they don't suffer from this problem. it's this computer.
exact specs can be given but before i installed a bigger drive i had clear video and direct x installed with no problems.
any suggestions ?

SOunds like a video overlay / hardware accelaration problem if you can't see any video in any tool. Check your graphic cards advanced settings and if you have two monitors(or tvout) set the one your watching the video on to the primary monitor.

And it's easy to test: Play a video in two media players at the same time. If only one is messed up you have a video overlay problem.

Ok I'm not the guy who had the original problem but I had a similar problem and I took your advice jagabo and played the video in two diffrent media players. WMP and VLC. Only one was messed up... so I have a video overlay problem.... how do I fix it? whould it be in the video card settings? I'm gonna go play around with settings and hope I don't screw anything up till somebody replies to this thread lol.

EDIT: ok I got it... for some reason the Saturation and Gamma were set to 0% which as you can probably tell jacked up the image pretty good.
