Okay, I've done a lot of searching and can find almost no info regarding this... hopefully someone may have an idea. My Windows 7 machine has streamed music to my 360 flawlessly through the Xbox dashboard since day one... Now, out of the blue, my xbox constantly loses connectivity with my PC. It still sees my PC, but when I click it to brose music... it just says "connecting...." etc until an error appears. It took much trial and error, but I believe I see the issue. It appears my "Turn on Media Streaming" function keeps resetting to "off"... I'll switch it to "on"... go back, and my Xbox will see the music and start playing it... by the time I'm halfway through a song, it just stops playing and won't connect to my PC again. Sure enough, when I go back to my sharing center, it says Media Streaming is turned off... Media Center works fine, but I cannot get this to stop happening when using my 360 dashboard. It has worked for months flawlessly. I'm not aware of any software or updates I've installed recently that could have affected my PC in this manner. Any suggestions would be greatly appreciated. Thanks. Andy.
