I upgraded my apple tv last night to the latest and greatest firmware. I noticed the new sort be genre tab under my movies but the only the movies I have purchased sort out in to genre. all of the others are under Unknown. So I went to Itunes and added the genre in on the info page. But it is still not sorting out on Apple TV. I also saw that there is some new parental controls, such as allowing nothing more graphic than PG. Where is that rating info stored? I have converted many movies and would like to add that info in. Would like to keep my 4 year old from watching scarface again.
I don't know if it can be done in itunes, but so far I have been unable to do it. However, one program that would allow you to add genres and ratings is MetaX. Also, the movies will only be resorted into their respective genres on the apple TV after you resync it.
