Re: Windows Media Player Error
VLC (VideoLAN) is a very powerful player and I've began using it everywhere, but this sounds strange for WMP to do. Is this a specific file you are trying to open, or any video file? play with multiple formats (AVI, MPG, and new and old WMVs, mainly), and out of curiosity tell us whether or not you have any trouble with audio formats (mp3, wav, midi, et cetera).
Oh, and if it is just one specific video or type of video, I highly recommend VLC --download it, and run the video with it. It not only can read a vast amount of formats (even ISOs of DVDs!) but if a video file is corrupt, it can still read some of it, and it attempts to reconstruct it.
