I not sure if the Win10 fall creators update, version 1709 has something to do with it. After this latest win10 update, I noticed that the "play to" is missing from the menu when playing my videos in PowerDVD 15 ultra. It was working fine before the windows update. On another computer, with a freash installed of win10, version 1709, PowerDVD 16 ultra shows "Play to", but it would not detect my Chromcast device. I contacted Cyberlink tech support for assistance and have yet recieve an answer. Anyone has the same problem?
