DVD Ripper dvd ripper. Settings ?

[torzen50]

I have just purchaced dvdfab copy/ripper, because i have to move a lot of dvd´s to my iphones/ipads.
But i am confused about which settings is the best.
I have an iphone 4, iphone 5, ipad 2 and ipad 3.
Is there a setting that works on all four units ? Which is the best ? (iphone, iphone4.h264, iphone5.h264.1080p......ipad.h264, ipad3.h264......???)

One other thing. If i want to see the movie via my appletv3, i suppose the setting is apple TV, right ? Is the quality much better than if i use the iphone or ipad settings ?
Sorry about my novice questions.

Thanks

Tor

You will have to choose the lowest speced profile which I think is the iPhone 4.

That should also play on your iCrap 3.
