I've been trying to figure out away to sync my movie library that is slowly becoming to big for my 2TB drive and will be flowing over to an additional 2TB drive soon. What I would like to be able to do is have iTunes sync with both libraries on the two HD's at the same time so that my Apple TV will display all movies when sync with iTunes. My understanding is that iTunes 9 still doesn't have the capability to sync with multiple libraries. Is there a 3rd party software for iTunes that will do this? I'm trying to avoid having to sync iTunes with different libraries when I want to view those movies.
