when the PS4 was released it had HDCP enabled and it could not be turned off. There was a patch released to remove HDCP from the PS4 a long time ago now. Unfortunately the same update was not released for the PlayStation 3 and it unlikely it will ever be done now that Sony have moved on to newer systems. It is not possible to disable HDCP on the PlayStation 3 and likely never will be possible. If you want to be able to record gameplay on the PlayStation 3 you need to use component cables. If you use a capture card like the hauppague one for gaming it will give you all the cables you need to be able to record PS3 gameplay footage.
