MP4 issues

Hello very new to this, tried reading some similar threads about MP4s not playing on the media player, but can not understand how to fix this.

If i try to play an avi file, an error pops up to say ‘unable to play file’ but when i try to play my mp4 file, it tries to load then just goes back to home page.

Can any one help?

So AVI and MP4 are both “container” fomats, not audio or video formats.

Please post the full TEXT output of MediaInfo for some files with which you’re having issues,

Hello Tony, thanks for replying, ive actually figured it out, and changed the codex to mpeg4 and now it works!

Thanks again!
