Although Windows Media Player is becoming increasingly outdated, quite a few users still utilize it for playing videos and audio.
However, the reality struck when users see that Windows Media Player cannot open WAV, MP3, MP4, AVI, MPG, MKV, and MOV videos and music for some users even though the software supports those file formats.
Why can’t I play video/audio files on Windows Media Player?
1. Switch to a different video player
While Windows Media Player is still a solid video player and it does come preinstalled with the Windows OS, it lacks many of the tools and features that third-party video players have,
That being said, one great alternative to Windows Media Player is the Winx DVD player, a video player for both short 5 MB videos as well as full-length movies from copy-protected DVDs.
The interface is extremely simplistic, so you can enjoy the movie more and worry less about audio and video adjustments.
As for versatility, this media player can easily handle popular formats such as AVI, MP4, DivX, MPEG, RMVB, VOB, WMV, Xvid, and more.

2. Fix corrupted video files
Sometimes the reason behind a video not being played back is not the video player, but the file itself. As such, if you notice that multiple video players don’t work on it, then maybe you should consider performing a video file repair.
With that in mind, we recommend that you try Stellar Repair for Video to restore your precious video files.
- Download and install Stellar Repair for Video
- Launch Stellar Repair for Video, and click the Add file button on its window.
- Select a video file to repair.
