I'm sure this has been asked before but any help appreciated ....

I've just bought a second hand Apple TV which I've been told is full of music. I will be connecting it to a network with 2 PCs - no Macs.

Can I copy the music from the Apple TV before running iTunes cause I believe that when I go and run itunes it will remove what is on the Apple TV and replace it with what is in the library in itunes on the computer - as it does with my ipod.

Can you reverse sync it or can the files be copied off the Apple TV.

Thanks in advance
