Dual/Multi Audio Dub Anime

since there are some anime that have two or more audio dub like Elfen Lied, i suggest don't include other audio dub in re-encoding so the file size will be more lessen and those audio that was not included will be posted in mp4, mp3 or etc format only here in forum and if there's someone like/preferred another dub they can download those other available audio language and merge it using mkvmerge tools.

i don't think it's as simple as merging it with toolnix especially when dealing with ordered chapters. good suggestion though.

For movies and ovas is possible to use patches, the problem is when there're multiple episodes and like Kenjo said, in ordered chapters it might cause troubles, even though it's not impossible (it requires some dedicated time to prepare the patch for each file) but I bet there will be a river of error reports (there're already many problems with normal patches... xD).
