Are the movies and tv shows stored locally or through network? Not that it matters that much but enjoy asking that question.
I think I understand your problem though, as I had the same one.
What you need to do first is define your source.xml
example, using multi-pathing for movies as you have to different harddrives for that.

No if you go to the Aeon settings screen and do what K-Flex suggested it should work. I say should, because for me it still wouldn't work and only worked once I had modified the homescroller.xml. But hopefully you won't have those issues.
