Can anyone recommend a tool that will scan a video file and report whether the file itself meets Apple's requirements for playback on the ATV? As I convert my library from MKV to MP4, I am finding that certain movies don't stream so well to the ATV. This typically happens with the larger files (>2GB). The symptoms I am experiencing are quite varied but they all make viewing movies a bit of a hassle. FWIW, all of my movies were converted using MP4Tools and in most cases, the video files were simply converted by MP4Tools. Only a handful of movies needed to be re-encoded. Thanks in advance for the suggestions.
