How to play MP4 files - easy - the solution

[JTBM]

I have just spent 2 hours trying to play MP4 video (AVC + AC3) (Windows XP and Vista)

MPC showed the movie flawless - with no sound.

SMPlayer played the sound, but no picture.

At this point I was releaved that the file is OK.

I was not able to find a program what would play the crappy MP4 format.

However I was stupid not to think of it before, I am using MKVtoolnix since mkv was invented - I simple converted the MP4 to MKV using MKVtoolnix.

Now everythink works as clockwork. No more stupid, unknown, non-working videoformat...

So don't try to install 20 programms, codecs, whatever, don't read through tons of forum, just convert the damn MP4 to MKV and it does work...
