I have windows 8.1 and wmc. I want to know why you do not allow powerdvd 16 to insert an option in the wmc start menu? I see Cyberlink PowerDVD 15 but no PowerDVD 16 option. WMC is still supported in windows 8.1 so I can't understand why you don't allow powerdvd 16 to be supported in 8.1. Are you working with Microsoft to prevent HTPC to function with WMC???
