I have searched and searched and can't find an answer. I have a mini with an external HD with AIFF and AAC copies of all my music. With coverflow and the iPhone remote app I see both copies. This is fine on just the mini as I use a smart playlist to play music. On AppleTV and with the iPhone I want to just get the AIFF files. Do I need to keep two libraries? If so I can't figure out an easy way of transferring them. I would like to avoid sifting through four hundred albums and copying and pasting tracks. Any suggestions? Thanks in advance.
