hi. i've tried searching this one, but i can't get an answer. If i use an Apple TV (160Gb) synced from an iBook, but the files are on a external drive, will i have a problem..... i know that to sync i have to connect the external drive, manually select the files to transfer, etc..., but once the 160Gb are full, if i unplug my external HD from the laptop, will the ATV then delete the files..? or as it's now disconnected will the ATV just happily act as a HD based media player...? any help..?
