The .xml-files are still there, but the WD TV doesn’t load them. I found another thread on the exact same problem where the solution was to go into the settings and clear the media library, but that didn’t do much good. In fact, it made the .jpg poster-images, which previously loaded, to disappear as well.
Any help would be greatly appreciated. The prospect of having to re-download content info for 131 movies all over again is not particularly appealing
