When i play AVI's in Windows Media Player I used to be able to adjust the brightness from within WMP "Show Enhancements". I have the slider bar option, but sliding it darker or brighter does no good. As soon as i slide it one way and let go of the mouse buttun it just goes back to default. Anyone have any suggestions? I have tried reinstalling Codecs. No luck. Im acutally using no codecs now and still get the same results.
