I feel sorry for you, bro. I'm currently working on another article/sticky for the Mac Forum on how to get the most out of your older iDevices running iOS 5 (video/amv relevant), but it largely requires jailbreak and a few other things which Apple has locked down in iOS 6 and on the iPhone 5.
I didn't expect iOS 6 to be such total crap, or I would have worked on this article/sticky before people started jumping on the iOS 6 bandwagon because there is currently no way to downgrade.
tl;dr DON'T UPGRADE TO iOS 6 IF YOU WANT TO KNOW HOW TO RUN 720p/1080p 30FPS on your iPad/iPhone/iPod Touch without reencoding!!!
I put this here so more people would see it. Lots of non-Mac owners own iDevices.
