Since my whole house is “Apple’ed” I rip all my DVDs with Handbrake.

I was wondering if there is a way to add that little rating symbol and additional information like Producers, Screenwriters and Actors as it is found in m4v files purchased through the iTunes Store. I create regular AppleTV m4v files with Handbrake, but if I option-click a movie created in this manner, there is no “Get Information” option. Any ideas?
