Help! Please!Clone DVD

[Marsup 72]

Hello,

I wonder if somebody could help me please?
I was wondering how i could copy 2 DVD (3 episodes of 20mn each), in only one dvd, using clone dvd.

I think i've tried everything (actually probably not, hahaha)
but i can't and i don't want to use 2 dvd (what a waste of space!)
I'm desesparate...

thanks
Anse
