I just got a program that can transfer my DVDs to my Mac in different formats. I can easily check off "iPhone", "iPad", or "AppleTV" each of which is saved into a different size (most likely depending on the standards of the device). I have saved a movie with the iPhone standards & it looks great on the iPhone but is grainy on the AppleTV (expected). Is there a universal size that I should transfer it to so it will show up great on all formats? I hope so because right now I am transferring each DVD into 3 separate file formats for viewing on each device. ie. iPhone, iPad, AppleTV. Thanks in advance for all the help.
