Listen to Music, Watch Videos* & View Pictures on your Xbox 360
You can stream music, pictures, and video to your console from any Windows XP or Vista based PC on your network. Use the Zune software or Windows Media Player 11 to stream content to your console.
Zune or Windows Media Player, how do I decide?
Choose Zune if you already have a Zune device, or download music from Zune Marketplace. You can share all of your music in your collection, including Zune Marketplace content.
Choose Windows Media Player if you want to play content from other online stores.
You can install both Zune and Windows Media Player 11 on your PC, but your console can only connect to one at a time.
