unsplit one movie from 2 dvd-r to one

[johnjohn]

ok.. I initially did a full disk backup of signs on to 2 dvd-r using dvdxcopy and ifoedit(to remove logo and warnings). so now I have 1 disk with 90% of movie and 2nd disk with 10% movie with other extras.. Now I would like to put the whole movie in to 1 disk and the 2nd disk for extras( It is possibleto fit on one disk if I remove the subtitles and second audio track while keeping the menus ) How do I do this... by keeping the original menus and chapters to combine movie part and menus from two disks to one using basic tools like ifoedit, vobedit etc...
also another question what can I use to covert ac3 audio to mp2 or mpa to use in sonic dvd complete application since dvd complete doesn't support ac3 streams...(can tmpgenc do it? how?)
any help is appreciated ...

Removing an extra 2 channel audio stream and subs isn't going to free up 500mb. You're going to need to consult one of the recompressing guides.

thanks for reply.. I forgot to mention that I'll also remove 1st intro credits chapter about 2-3 minutes which brings the size to fit in 1 dvd-r... anyway I would like to first get the 2 disks into one first before I do more clipping
also any help with my second question on ac3 to mp2?

Look for BeSweet or ac3decode.
