@Reto @Fabian I don't normally make UHD to BD conversions but since I upgraded my videocard I decided to do some experimenting. CloneBD 126.96.36.199 x64 beta will not create UHD to BD output that will play on my Oppo BDP-93. Method of encoding doesn't matter. Both CUDA & QuickSync result in an unplayable backup. I tried playback from a burned disc and AVCHD folder. The BDP-93 begins loading as normal and then simply gets hung up. The front display shows: TT 1 00:00:00 When this is happening the buttons on the front of the player and the remote don't work except for the power button. I can't go to menus, the Home screen, etc. It's important to note that this is not a hard lockup requiring you to press and hold the power button to force a shutdown of the player. A simple normal press of the power button on the player or the remote immediately powers down the player like a normal shutdown. Now, the really interesting part is that the backups play fine on my Oppo BDP-83 but simply refuse to play on my BDP-93. BD to BD backups will play on the BDP-93. UHD to BD won't.
