My mother is 83. She watches 1 channel on TV. She would like to watch some of dvd's (some blue ray) but switching inputs is confusing for her.

I was thinking a blue ray/ tv combo, but they are super hard to find.

Any thoughts on something that is super easy to switch inputs?

What i would like is if the dvd is turned on, tv auto switches to that inputs. If want to go back to tv, hit channel up.or down (or just as easy)

Anybody know.of something like that?
