For the last couple of years, I have had my xBox 360 streaming video from a computer elsewhere in the house. It's been a trouble-free experience - until a few days ago. Suddenly, all of the Media Center library folders appear to be empty, although the files are still there, in their original locations, on the computer. I've tried removing and re-adding the relevant folders to the library; I've even tried uninstalling the extender on both the PC and the xBox. Nothing works. Each time, the adding files routine appears to run successfully but once it finishes, the folders remain empty.
I'm getting extremely frustrated at this point, and would be very grateful for any and all suggestions.
