If the original mkv file has both h.264 video and AVC audio, you'll want to use something that just changes the container instead of re-encoding the video.
FFMPEG will copy the video and audio into a mp4 container using a command like this:

This isn't true either. DiVX is a codec that is MPEG-4 Part 2 compliant, but is developed, and thus "owned" by DiVX Inc. http://en.wikipedia.org/wiki/DivX
There is also MPEG-4 Part 10, which is used by codecs like h.264 and "DiVX HD". So just because something is in a "MPEG4" codec doesn't mean it's DiVX, and software/devices that claim to be "DiVX" compatible may not be able to play all MPEG4 profiles.
