When playing music from my win7-based music library, the Apple tv will play one song and then instead of continluing with more mlusic, will merely indicate what the next song in the shuffle lineup will be. No music ensues. ,

I am having difficulty getting my win7-based music library to play using my apple tv. The music library shows up and when I click on shuffle songs, one tune will play, but nothing after that. The next fune title appears, but does not play. I have noticed that in the library listing it shows a listing of photographs from apple tv, but no reference to music. I always make it a point to be sure tha thome sharing is turned on. This is my second apple tv unit and software is all up to date, as is itunes.
