Some of them I loaded directly in to iTunes from DVDs. Some of them were 'acquired' via the interwebs. Some of the movies that have been 'acquired' play just fine and other don't. For example, I have Monster's Inc. that I loaded directly into iTunes from a DVD for my daughter. Sometimes it'll play, other times it wont.
I've been using iSquint to convert avi to mp4. Should I have checked the H.264 box? Do you think that would fix it? But it still doesn't explain why, when a movie is loaded into iTunes via DVD that sometimes it works and sometimes it doesn't?
You're awesome for answering and helping me. Thank you so much.
In case it's any help at all, these are the specifications used by the Apple TV.
