I've been spending the last weeks trying to get the best solution for hd movie storage for my apple tv. Here is what I found: Open ATV and replace internal hdd ssh ATV and connect external hdd (though it still requires opening ATV) sharing new iTunes library from external hdd through AEBS between ATV and my iMac or MBA (never considered option) The only problems that I see in the last option are: would it be possible to share a library in my TV from an external hdd connected through AEBS would it be possible to save in different formats than mp4 and still open them in the ATV would the 5ghz n wi fi streaming of my AEBS solve the usual choppy streaming for HD movies? Any guests? opinion? suggestions?
