I've been having pretty good success encoding to MKV files using Handbrake 9.4 and using the Legacy/Classic settings but limiting the video to 600kb and the audio to 2ch aac @ 128kb.
There are other threads in the forum regarding MKV encoding for the original XBOX with heaps more information on thios very subject, so it might be a good idea to take a look there.

I am addicted to documentaries posted by MVGroup. Unfortunately many good ones with subtitles are in HD X264 + AC3 audio MKV. So, it is some time that I successfully re-encode them to Xvid with MP3 audio. It took me some time to find how to do it. So here you are, the secret of re-encoding MKVs

Programs that I use are MKVtoolnix + gui to open the MKV files and extract their Audio, Video and Subtitles.
Then with Avc2avi in command prompt I convert the .H264 to .AVI with correct frame rate. It has a bug that when converts a 29.970 video, it converts to a 29.969 file. In this case I use the AviFrate program to set it back to 29.970. BBC documentaries are 25.000 and has no problems converting them.
Then I convert the AC3 audio to MP3 with BeSweet. Create an Avisynth script with one line, AviSource("path to\Converted.avi"), and run Gordian Knot as usual and re-encode them to Xvid. You really need this script for the H264 to AVI converted files only.
It works great and I run them in batch. One thing not to forget is to set the Aspect Ratio of GKnot to 1:1 ! It has got me many times forgetting it is a Re-encode not a normal encode.
I adore my Xbox & XBMC and will not let it go yet. I hope this helps you.
Oh, Happy New year
