Most of my videos were quite dark after I installed
windows media player 9. The older versions of wmp played
the video just right. For DivX videos, I could set the
brightness and save them in the codec settings so they
could be used everytime I play DivX videos. However,
there is no such thing for mpeg files. There is a video
setting in wmp9 to adjust the brightness but this setting
resets each time the media player is closed. Is there
anyway to save the settings?
