Like all media files, Windows Media Videos (WMV) can become broken or corrupted. This could be caused by a virus, a mistyped file name or a bug contained in the video files itself. Several programs exist to fix corrupt WMV files. Running any one of these should clear your WMV of any bugs or viruses and get it playing in Windows Media Player or any other WMV-compatible application.
