Fitting 3 DVD into 1?

Tweet

My mother loves Golden Girls and I want to make a copy of the dvd that i own. However, my mother does not like to press play or select a chapter and what not, she just wants to put the dvd in and have the show play. Golden Girls season that i own has 3 discs, is there a way that i can just extract the episodes on 3 discs and burn them on to 1 dvd, with no menus and extras? she just wants to put it in and play it. I thought about recording the episodes on to a VHS but wanted to find out if putting just the episodes on all three discs onto 1 disc was possible. Thank you for your help.
