Please help! Want to recode 3 dvd movies to fit 1 DVD

Hello, I have a TV series that is 3 DVDs long that I have ripped in TS video folders. Is there any programs out there that can recode all 3 of the videos to fit into one 4.7GB DVD? I have TMPGenc DVD rebuilder and DVD Rebuilder with CCE but cannot find a guide anywhere to do this. Please help me thankyou very much.

So you want to put 3 x 8gb dvd’s on to 1 x 4.3gb DVD ? I wonder why you havent seen any Tutorials on how to do this?
