I'vbe had a new latop for a few months and suddenly it now doesn't want to play Mp4/M4V files.

quick blast on google and i'm faced with loads of this that and t'others to download.

Any ideas of best way round this that isn't going to make me download malware/adware/bloatware and whey the hell has it just stopped playing via Windows Media Player.

VLC won't open them nor anyplayer.

It won't open them or won't play them? No error messages? It just sits there ignoring the fact you've tried to open them with absolutely no other activity?

It's 100% all mp4 / m4v files and 0% any other audio affected?

The "codec" thing that stenhousemuir suggests worked for me.

Seems like lots of MP4 have some form of encoding on them that WM amongst other things doesn't like.

As you can probably tell, I'm not overly familiar with any of the correct terminology!

And if it's a codec issue then there's more elegant ways of fixing it than K-Lite Mega which will install every codec ever known to man ever. I mean, you might want to do that and it could well work, but I'd rather diagnose it than guessing.

It's not that mp4 has encoding "on" them so much as in them. It's a container format, what's inside it could be any manner of data.
