Dvd10 To Dvd5

I WANT TO BACKUP A DVD10 (EACH SIDE HAS ABOUT 2.7GB) INTO A DVD5 WITH
A LITTLE COMPRESSION AND BY REMOVING SOME UNWANTED ELEMENTS.
My problem is that i don’t know any software that can do the write of this 2 sides into a side?
I have transfer the 2 side into the hard disk

DVD Shrink can combine 2 or more titles into one disc. If you’re interested, I’ll give a brief guide.

Yes i’ll apreciate it very much

cdfreaks has a guide here.

It can be done but you will have to re-author (which means you will lose the menu).
