I have a similar question to the now solved post here.
I've imported a folder that has kid appropriate music videos via Settings>Local Content>Video Sources. Under Library>Music Videos I've changed the visibility to "Both" and added Genre Tags of Family and Children. I then created a Virtual Channel, added the Music Videos Library to said channel and set it to Random Sort, creating a Kid Friendly MTV channel if you will. The virtual channel is accessible fine but not when the Kids filter is chosen.
Am I missing a setting or something else that would get this working?
