I have a large collection of MP3 files on my Mac that I play using iTunes. What I would like to do is store these and have access to them using my home theatre. I like being able to use iTunes to sort my collection so would like, if possible, to keep that ability in anything I purchase. I've looked at the Apple TV and the Western Digital Live Media Player. It almost sounds that the Western Digital item also needs a hard drive connected to it for storage, it does not store files itself.
Is what I want possible? If so of the two, which is the better way to go or is there something else I should consider.
Thanks
Ron
