Double sided source DVD editing & add audio track

[BFLM]

Hi all DVD guru`s,

I have "Friends" double sided DVD.Each side contains own menu with "Play", "Chapters" ans "Languages" buttons.

1, I would like to prepare 1 normal 4,7 gb DVD and keep present menu and complete VOBs (video, audio and subtitles streams) without difficult reauthoring.(I know how to compress it than :))
2, Add another audio track from different source to each of VOBs and keep all from point 1.
3, Add to the dvd menu possibility to choose added audo track in languages menu.

Which software I should use and pls guide me little bit.

Many thanks!...and sorry for my english

I think you could do with dvdlab pro ( main movie )

you can insert an audio trak on vob but I think problem would be sincro.

Anyway you would loose menus , I think you should remake menus .

exist any tool which offer to load complete dvd content and provide you possibility to simpple edit content? (add/remove tracks, edit menu looks etc).

I tried dvdlab pro, but I have to demux everything and put it back, included subtitles.Again create dvd menu using original basis etc..
