Because of ongoing debate in this forum about the source of stutter/judder using Infuse on Apple TV and the complexity of the topic i would suggest the addition of a Infuse playback statistics overlay with information about the current file playing.
Something like this, especially the Control+alt+shift+D hotkey.
On the Apple TV the overlay could be invoked through a menu option or a special (secret) button press on the remote (if possible).
I think that the following information (more or less if possible) would be of interest to debug the ongoing complaints:
Source framerate/Apple TV framerate
Source muxing info (MKV etc.)
Playback demux info (when available)
Apple TV CPU/RAM info (if possible)
In my opinion, there is way to much guessing and false information going on in this discussion and we need some tools to cut through the different issues and bring back some facts to get to the source of the different issues being discussed.
