Creating DVD with new audio.

[CraigBjorn]

Most of you have heard of synching Wizard Of Oz with Dark Side of the moon, and I would like to do something similar.
What I need some help with is both, getting the DVD (fight club) down to a small enough size (removing all audio, and menus, but leave subtitels) and resynching it with different audio. The guides here have been very usuaful for the first part, I think what I'm going to need to do is just remove alot if the info inside of the first few ifo's with ifo edit, in order to get rid of the menus, but I'm not entirely sure how to add different audio and keep the subtitles.
I've used Avisynth before to get different audio, but I've done no work what so ever with doin that in combination with subtitles and removing everything else.. any help would be appreciated

I already asked for such (with no success).
What i want to do is exchanging one (or more) audio stream(s) in a VOB by a low-bitrate version to save some space during backup.
What you want to do is replacing one audio stream by another. For the technical process it's basically the same.
