Replaced my HC-250 and all is working. My HC-500 that has all my music is working (music plays) as well but will not perform a SCAN. When trying to SCAN it does nothing. So it is not possible to add new music. Looking at the HC-500 direct (Windows explorer) I can see new music that was added using the ADD function. But it will not appear in the Media > Home Controller HC500 music list (screen shot attached) I assume this list is built during the SCAN process. Any ideas on how to get SCAN to function?
