I have the latest codecs loaded on my laptop, but I can't seem to get .AVI files to play right. I get awesome video - just no sound. I have tried the same files on my desktop and they play just fine. HELP. I want to be able to play some of these...and I'm going to rebuild the desktop soon...so I'll lose the ability to view these on it. Any ideas or thoughts. I'm running XP, with the latest and greatest of DIVX and Windows Media Player.
