Multiple DVD's onto one DVD

[The Toe Cutter]

Ok I read the tutorial for putting 2 dvd's onto one dvd, but here is my situation. I want to put some of my fiancee's excerise DVD's (each about 30 minutes each) onto one DVD. So I don't need to shrink them or compress, just put multiple episodes on one DVD.
So in DVD Decrpyter do I just read the 3 DVD's and save as 3 separate VIDEO_TS.ISO files. Then just put all VIDEO files all on one blank DVD-R?

What is the best/ asiest way to do this?

Thanks for the help, I'm a newbie at this.
