My network has quite a few devices on it, so I won't bore you with the layout.
But the main topic of my issue is that I have two WD TV Live Streaming
devices. My laptop is Windows 7 Ultimate 64. When I choose "Play To" on a media file to stream to either of the two devices, it says "Contacting network server" and then eventually errors out. I have gone through numerous things and all the "usual" stuff to try, but it errors out. I've reset all devices and computers, router, etc. Nothing seems to help. I also have a desktop Windows 7 Ultimate 64 and it can "Play To" absolutely fine.
Aside from the uPNP and Windows Media Player Network Sharing service, what else should I be looking for? I don't know what could be different that is preventing this from working on one system.
