Hi Bus Man,
I’d suggest you to refer the following articles for detailed information on media streaming:
Getting started with media streaming
**http://windows.microsoft.com/en-us/windows7/Getting-started-with-media-streaming**
Note: If you're using a digital media receiver, it might not support playback of all the file types your computer can stream. For example, your device might support playback of audio files but not video files or picture files. Also, your device might be able to play songs that you purchased from an online store but not songs that you've rented through a subscription service.
Stream your media to devices and computers using Windows Media Player
Change settings for streaming media in Windows Media Player
Using the Play To feature to stream media

Hope this helps!
