This feature works with recent DLNA-enabled streaming devices, though you should check with your specific hardware company to ascertain compatibility. For example, even though the Xbox 360 isn't DLNA-certified, you can still reach it with Play To.

You can activate the Play To feature on HomeGroup PCs from within Windows Media Player. The process is handy if you have a PC hooked up to a TV or stereo, or if you want to push media on a networked computer in some other way. Here's how to enable Play To.

On the host PC, open Windows Media Player, pick Stream, Allow remote control of my Player, and click Allow remote control on this network. Henceforth, on the remote system that shares the HomeNetwork, you'll be able to right-click a playlist or file, select Play to, and choose the name of the remote system or media streaming hardware. You can even select Play to by right-clicking within the desktop, instantly starting a file running without additional setup.
