Backing up a movie over 2 discs.

I want to backup "The Office Season 1" but after DVD Shrink analysed it the compression for the first disc was greater than 4.37GB.
I then analysed Disc Two and that had lots of room. So how can I take two episodes from the first disc and transplant it to the analysis information from the 2nd disc?
Thanks for the help guys... I am new to this so I don't what to do. Cheers.

 

With dvd shrink use this guide :http://www.dvdshrink.info/splitting-v2-3.php

 

Used daddy's link. However using shrink is easy. I would do 2-3 episodes at a time. This way the compression does not kill you in terms of picture quality. As long as you don't care about the menu's
