DJ, another handy tool for MKV creation is mkvMerge. It comes with the mkvtoolnix pack. Its nice for muxing audio files into the mkv (like adding all the audio tracks you are working on).
mkvtoonix is fantastic - that's what I used to add all the PCM tracks I had to the MKVs I made of your V1 set, DJ.
