Q: Movie "was not copied... because it cannot be played on this iPad.

I have a movie that I ripped a long time ago to play on my AppleTV but since I still haven't gotten around to watching it I'm going to put the movie on my iPad.

In iTunes, I drag the movie onto the iPad to copy it (I am manually managing) and I get this error:

"[movie] was not copied to the iPad [name] because it cannot be played on this iPad."

So I select the movie and from iTunes' Advanced menu I choose "Make an iPod/Apple TV version" and I get the error:

"One or more videos were not converted because they are already in the correct format."

So I'm in a loop.
