Hi there. I'm wondering how I can store/keep movies I've downloaded from iTunes on my AppleTV, without having to keep them stored on my MacBook as well?! Obviously the ones I buy on AppleTV stay there..but I like to buy them on my laptop so I can also put them on my kids' iPod Touch(s)...but after awhile I end up with 100Gb of kids movies on my laptop?! I'll typically move them to an external hard drive for future access...but then once they're off my laptop and AppleTV starts to sync....they're all gone from AppleTV too?! I want to be able to sync from iTunes on my laptop to ADD new movies without removing all the others?! I'm normally pretty adept at figuring these things out...but this one I just can't find a solution for?! Help?!
