Way 1. Convert WMV to MP4 or Other Popular Video Formats

Converting the corrupted WMV file to a more widely supported format like MP4 can sometimes fix the WMV video not playing issue. This is because converting involves decoding original file and re-encoding it to a new format, which can fix small corruptions.
