i have a slow internet connection, of which i cannot change as it is all that is currently available where i'm living. i have downloaded quite a bit of movies onto my computer (into ext HD) thru itunes, while visiting somewhere that has a very fast connection. I would like to copy/transfer them on to Apple TV unit. Using the wireless connectivity of the apple tv and the macbook means it will take ages to synch the two units. is there a method for hardwiring them together so the transfer if movie files is done more efficiently?
