I have a duplex and I provide vacation rentals and enjoy being able to let them access my movies and music via an ATV in the unit but I want to turn off my personal pics without deactivating them from the other ATV's which use pictures as a screensaver. Put another way: Can I turn off pics on one ATV and not others on the same network, while still giving access to movies and music to all. But not my pictures, which I do want shared with the other ATV's on the network. I really appreciate the help!! Also, does anyone have a word of caution with letting people use my ATV or just general security issues with giving out my network password?
