Can someone help me solve the problem of my Windows Media Player ? I installed XP Codec Pack 2.5.1 on my XP yesterday. The Media Player was able to play two AVI and MPEG files first before the system got disrupted when it tried to play one other AVI file. The screen got all messed up and I have to shut down the system and reboot it. Then the Media Player couldn't play the two AVI and MPEG files altogether. In one instance, I got error code COOD1199, saying that the Media Player can't play the file. In other instance, the display said the file is being played; but there were no audio and video outputs. It seemed fine when the Media Player tried to play some other AVI and MPEG files. I have tried to reinstall the XP Codec Pack 2.5.1. But, that isn't working either. Can someone offer me some help ?
