Help converting mp4 AVC to mkv (with vorbis)

[Leo 69]

Hello guys !!!

I've searched a bit for what I need, but it's toooo specific to find this, and I thought it's better to ask you :)
I have a Nero mp4 videofile (AVC) and an ogg vorbis soundtrack for it.
I know I can use mp4muxer but the resulting file is hardly playable anywhere (Osmo doesn't help either). I want to put both streams into
matroska to enjoy the film in Mplayer. What exactly do I need to do with them ?

Thank you very much in advance.

Get mkvtoolnix (http://www.bunkus.org/videotools/mkvtoolnix/), load the video and the audio file (evtl. have a look at the options if you know what you are doing, otherwise leave it as is) and start muxing.

Oh, cheers. I actually wasn't aware of such an amazing GUI for Matroska. This thingy answers a lot of my other questions too.
Thanks God, there isn't any commandline at last :)

Huge praise to devs! Thanks a lot !
