The hardware decoder in the iPad and iPhone isn't that great. So I'm curious what you guys do for multiple device encodes? I feel its really inefficient to multiple copies of the same video however at the same time having a lower quality one size fits all isn't the best either. I notice a video that plays fine (for the most part) on my ATV3 at a ATV3, Normal or High Profile preset will not play on my iPhones and iPads (this was never a problem with my Android devices). I'll get artifacts like in the picture below and eventually the video was freeze while the sound continues to play. I only notice this with DVD's never a BluRay.
