Nah, there's already a problem with BD due to the number of audio tracks, additional stuff won't help. :) The best thing would be a 2 disc box and a cool cover.

Give multiavchd a try i got all the audio tracks working i ripped the streams and converted the video to an easier form for multiavchd to handle and it handled all the audio tracks fine and subtitle tracks. I can upload my project files or what not to myspleen and maybe someone more talented then I, can take a look.
