Oh, actually, I use AC3, not AAC. Also, CatBus is right, I'd like to use only one dubs per language (except English of course) and I always want to go with the most original one - like the new BD dub in my language is superior in most ways - far better audio quality, better translation, better pronunciation of the SW words and stuff but it holds no emotional value for me, so I'm still using the old VHS dubs.

But it's great if you want to provide your edits for people to mux in themselves.
