Mass demux and transcode from .aac to .mp3 in order to get playback on the old Xbox?

I have a crap load of videos that are x264 with aac audio. The aac causes problems in performance is there any program that mass demuxs .mkv and then mass muxs mp3 back into it?

It's the x264 not the aac.

This one has also been thoroughly discussed. PLEASE use the search button and put an effort into resolving your own problems before asking questions.
