Unattended multiple DVD play ?

Can I do this ?
I want a DVD changer that will play multiple commercial movies for me without any intervention on my part.

Most DVDs I’ve screened are packed with menus, previews and other assorted extras.
I just want it to play movies for hours on end - is that so difficult ?

Wonder why can’t I push the proper buttons after each flick ends ? If you must know, I’ll be asleep.
