I'm fairly new to ATV, as I just purchased 2 devices within the last month. I too am using HB, but quite honestly, I really have no idea what a LOT of those settings actually control. I'm trying to gain some knowledge here, but my head is still spinning reading your through your posts. Essentially, I would just love to get the best picture possible, keeping the original aspect ration for whatever movie, and coming in at around a 4-8 GB finished. Any help you can give me is greatly appreciated. I've tried using the iPad, ATV and High Profile settings, while making a few adjustments. Mostly, changing the setting from 20, down to 14 or 15 on that sliding scale under the video tab (3rd or 4th from the left), I believe. And I just started checking the Large file box, as a few burns didn't play in iTunes.
