ok i want to know if this is possible and if so what FAQ do I read to do this

I have these anime dvd's w/ two different audios (english and Jap) and w/ two different sets of subtitles (english and jap)

the dvd's are only about 2.9 gigs each so i want to compress two dvd's to one w/o the english audio and subtitles

what i want to do is create a top menu that loads up and says

DVD 1 - episodes 1 - 4
DVD 2 - episodes 5 - 8

when you click on dvd 1 it will go into the pre-made menu's/ chapters from that original DVD so I don't have to do any butchering of the beautiful menu's and chapters


now to the problem
it appears after looking through the vob files it appears that both audio tracks are stuck on the same vob file. I know how to get rid of the audio

now w/o losing any of the menu's from the original dvd how do I get rid of the english audio and subtitles so I can fit it on one dvd ?


I know how to rip the video and the audio and rejoin it into a file but how to I change that back to a VOB file while maintaining the original menu system ?
