I'm thinking of buying an Apple TV especially for its home sharing support. But I have a couple of questions about it: 1. If I set up the Apple TV using one Apple ID but my Mac or iPad is on another Apple ID, then will I still be able to stream movies, TV shows, etc from the Mac or iPad using home sharing? 2. If not, can I change the Apple ID I am logged in with on the Apple TV easily and quickly without a whole device reset or something big like that?
