I have had the complete set of slysoft software for years, I know I'm still learning a lot, but there's nothing yet that successfully removes Cinavia from any type of disc that will allow you to play that Cinavia protected backed up copy on any player that has the Cinavia detection system on the player.
Read my earlier response, I stated that you can back up a dvd, or blu-ray disc that has Cinavia and if the updates on an older player that does not have the Cinavia detection system on it, will, if it can, at it's current update, play a Cinavia encoded disc. However if the player won't play an original disc before being backed up, because of the current updates from manufactors, it won't play the back up either. I have backed up certain dvd's and blu-rays that don't have Cinavia and they will play on a Cinavia encoded player, because they did not contain the Cinavia encodeing to begin with. I think if you are able to play a backed up disc on your Cinavia encoded Sony player, you are backing up disc that don't have Cinavia on them, there are still a lot out there, but that is changing faster and faster all the time. Just wait until the only way you can ever watch a movie on your own disc in the future is through the uploading into the cloud (ultraviolet disc) and back to your T.V. That will be the time that backing up your disc will be extremly difficult if not totally impossible, because the encoding will only allow a disc to play after it has been okayed by the cloud which will have Cinavia.
