I just spent a lot of time looking through all the old posts on here and following advice and ive come to the following problem. I downloaded a movie onto my computer and the video looks great but with my original codec configuration i couldnt here anything at all. well i looked through a bunch of codec posts on here and tried to follow a lot of advice in them so i uninstalled all my codecs and just installed the following. Latest divx codec, ffdshow-20041012, OggDS0995, XviD-1.0.2-29082004, and windows media player codecs. well i went to try to play the file and now i have sound but its mixed in with this horrable scratchy noise. i can here the movie though its just really loud and horrable scratching. The video is encoded in Xvid format. Maybe im missing a codec or something. Anyone have any advice or instructions to help me? Thanks.
