If you're looking for full hardware decoding of high profile 720p H.264, or any 1080p H.264, you'll need different hardware. A stock ATV is not up to this task, regardless of what software it is using.

I have an mvixusa Ultio which can play full 1080p files. It's quite nice but I am partial to my Apple TV. In fact I am quite happy with the "main" profile of H.264 which shows up nicely on my ATV. The thing I was uncertain about had to do with "rumours" that Apple had not given developers access to the video hardware but reserved that access for its own HD ( which seems to be the main profile). To my surprise 720p files played well from nitoTV as long as I used the main profile. Since I have nitoTV using Quicktime I then wondered if Quicktime from nitoTV had the same capabilities as video played from synced/bought iTunes.
If it doesn't matter much whether the GPU is used, does this mean that XBMC can handle main profile video? It didn't seem to the last time I tried but perhaps they don't use the same video drivers as nitoTV?
