Are you accidentally looking at the old version of the movie in iTunes? By that I mean, once it is written you need to drop it in iTunes or let metaX do that. Then that's it, maybe you have to sync, but it will show up on apple tv.
That was the partial solution. On the ATV now, the image shows up as does the movie duration, but the description does not. For example, on movies I buy from iTunes, the movie photo displays for a couple of seconds, then shrinks to reveal the description and rating. But that does not occur with the MetaX movie. Do I need to select something specific for these to show up on the ATV?
