I've maxed out AppleTV and my MacBook Pro is complaining too (i.e. almost out of storage space). Is there anyway to compress music files in iTunes, and thereby in AppleTV/MacBook, to increase the number of songs I can store/access on AppleTV? I have 400+Gig of music. AppleTV ain't big enough!! Anyone? Alternatively, can I run multiple AppleTV's linked (which wouldn't address the MacBook issue)?
