I have an AppleTV, an iPad 2, and the new iPad ("4") with Retina Display. Using Handbrake, I have been creating 4 different versions of the DVD movie I am ripping via the presets: iPad AppleTV AppleTV 2 AppleTV 3 Is there any advantage to having all 4 versions of a movie? Or do you think I should stop creating every AppleTV version? Since I have the original AppleTV, will I run into any backwards compatibility issues if I discontinue ripping from one of the AppleTV presets mentioned above? I figure that the iPad version at least saves me some space on my iPads... Thank you in advance.
