Thank you Brionas brain and Perlas Draplin.

The steps you both gave helped me a

lot.

And resulted for the error in my Windows Media Player 12 to disappear.

Thank you so much TechyV.

That’s because not a single version of Windows Media Player, not even earlier versions, supports the M4V video format (*.m4v). Windows Media Player can play this format if the codec is available on your computer. A video codec is software or it can also be an electronic circuit that compresses and decompresses digital video. A video codec converts uncompressed video to a compressed form or format and vice versa.

In video compression, the term “codec” means “encoder” and “decoder”. In digital video, every file format uses a particular codec or video codec like for instance, an MP4 and AVI video. There is one codec for the MP4 format and there is one for the AVI format and you cannot interchange them.

If you try to play a specific video format and its codec is missing from your computer, you won’t be able to play it or the media player won’t be able to play that video. The codec designed for that video format must be installed first. One way to install different video codec is to install popular media players like the VLC media player.

Another way is to install a codec pack like with the K-Lite codec pack. Try downloading K-Lite Codec Pack Mega. This mega variant of the K-Lite codec pack is the largest of the four variants: basic, standard, full, and mega. This codec pack provides everything that you need to play all your audio and video files.

This codec pack also includes ACM/VFW codec which can be used by video encoding/editing programs. This codec pack includes Media Player Classic so you can immediately play your files. The latest version at the moment is K-Lite Codec Pack Mega 15.1.6. For Windows XP Service Pack 3, the latest and last compatible version is K-Lite Codec Pack Mega 13.8.5.

You can also use MPlayer for Windows or download the latest VLC media player to play M4V files.
