Why? What exactly is wrong with Matroska? Almost every media player these days supports it just fine (as has been the case for a while now) and it's a great deal more featureful than the mp4 container. (Embedded subtitles, file attachment support for extended cover art and related files, DVD-type menu support, etc.)
