I have some .avi video clips that I have downloaded over the internet. But whenever I try to play them via Windows Media Player, I get messages that WMP is requesting a codec and then that there is a error downloading the codec. Then, all I get is audio. I have tried other programs to run the files but I get the same result with just audio and no video. Can anyone tell me why this is and what I need to do so I can see the video?
