How to burn multiple episodes unto one disc?

[smudgebucket]

While I was backing up my copy of Deadwood Season 2, I wanted to put one episode from Disc 3 together with one episode from Disc 4 unto one disc. I have a single layer burner and I thought that this would increase the quality from approx. 60% to near 100%.
Basically, I was unable to figure out how to do this and retain menus or create a new menu that would allow me to access the second episode without having to fast forward through the chapters of the first episode.
I created a separate file on my harddrive for each episode but couldnot figure out how to import them both to Clone DVD to burn together.When I imported the second episode, the first was removed and vice versa.
I used Nero and got them both on one disc but without menus. I would really rather use Clone DVD to do this but I need some help here. Any help would be greatly appreciated as I am fairly new to this. TIA

No "join" or "merge" feature exists in Clonedvd. So, you can't.

I'll move this thread to the third party products forum.
