I am having a problem playing my newer AVI files on in windows media player. The older AVI files play, but the new ones are starting to give me problems. They were playing fine before but have now started to play in slow motion. The sound is normal, but the video plays very slow. The play speed settings are set on 1.0 but won't change if I press normal fast or slow. My computer has an AMD 2 ghz chip, 4 gigs of ram. Any help would be appreciated!
