I don't have an ATV yet but plan on getting one soon for HD rentals. I also have some movies converted from Visual Hub. I've imported these movies into iTunes and they play without a flaw - both video and audio. I'm not sure if I have additional codecs installed (I probably do). So the question is, if the video and audio play fine in iTunes (and Front Row) after importing them to iTunes, will it be guaranteed to play on ATV?
