SOLVED: Windows Media Sharing gets SLOW after installing Zune
We came back from Tanzania with over three gigs of photos and looked forward to having friends and family over to watch slideshows. We usually run the slide show on the Xbox360 talking to my main PC running Windows Media Sharing Service.
I chose to setup our home network using wired 100Mbs Ethernet, rather than wireless as our main "backbone" as I find even the fastest wireless totally unacceptable for large file transfers. Small things like the ReplayTV and a few other appliances are wireless, but every room is has plates in the wall with at least two drops, and there's a formal wiring closet in our linen closet with a punchdown block so I can rewire the house. Maybe one day I'll post on all this.
Anyway, back to the point. The pictures are 7.2 megapixels so they are 4-6 meg JPEGs depending. For last year the Xbox360 has been able to pull down a picture in less than 3 seconds, but just this last week it's taken 10-20 seconds, sometimes longer. Of course, this has significantly cramped our slide-showing style.
I'm a firm believer, when debugging, that something must have changed. So I sat down and puzzled on what's changed on my machine.
Then I realized that the only thing that changed was the addition of the Zune. I puzzled when I installed the Zune why it'd need another 'Sharing Service' - It installs the Zune Network Sharing Service. I didn't think too much about it, but I remember wondering Why do we need another uPnP service? Is the Zune THAT different that it can't just talk to the regular Windows Media Sharing Service.
Long story short, I ran "services.msc" on my Windows Vista machine and set the Zune Network Sharing Service to Manual, and stopped it. Lo and behold, the Xbox360 suddenly could pull images down as fast as before. Your mileage may vary, but if you have a Zune, you might consider just disabling that service all together. It certainly has a problem with the Xbox, or the Xbox has a problem when it sees two seemingly identical uPnp servers on the same machine.
