I just finnished building up my new computer. Just for fun, I decided to pop in a CD with a regular old .mpg on it and ran it in Windows Media Player. Much to my dismay, the entire image is extremely dark and the colors look terrible, as if my computer was running 8-bit color. I used the contrast option in WMP to see if I could brighten the image, but even that didn't work. I have also tried using the WMPC included in the KLite Codec pack with the same outcome. This leads me to believe that the issue is with my computer's hardware or software drivers.
I'm running a BFGTech Nvidia GForce 7900, with all drivers installed. Games, such as Half-Life 2 rune smooth as glass on it.
I tried getting a screenshot of the problem, but printscreen doesn't display video when it's used.
What's up with this computer?
