Help burning double-sided dvd to one 4.7 dvd, please

I searched the forums, but didn't find anything on this (maybe I'm using the wrong search terms), so please excuse me if it's already been asked and answered.

I have a two-sided DVD I'm trying to back up. I ripped it using DVD Decrypter and created the VOB, IFO, BUP files for each side in 2 different folders, which together equal approx. 8.52 GBs. While I have backed-up other discs (one-sided) to a 4.7 DVD-R, I have never done it from a two-sided one.

I don't understand how to get both sides into InstantCopy since each folder has files with same name (i.e., VIDEO_TS.IFO, VTS_01_0.IFO, etc.). Is there a way to do this, or do I have to put each side on its own DVD disc?

Thank You.

 

use dvd-shrink re-author function

click on open files, drag movie 1 over, let it do its thing
click on dvd browser and drag second movie over to re-author window
click on backup

 

Use a program called DVDshrink, it's free and it does what it says on the tin.

 

Thanks, to both of you!

Thats going to be alot of compression.
Keep it on two disks. 50% or higher I have problems
with the video quality.

Just a thought
