[QUOTE=platinumsword;2667101]People have tried to revert back to factory default settings with no success. Even if you mange to get back to that point, your ability to play future Blu-ray titles will slowly diminish because firmware updates will be required to play them. As of right now circumventing Cinavia protection for the average joe is not attainable. There have been workarounds discovered but they are by no means perfect and do not totally eradicate it.

I am checking eBay and Craig’s list but it looks like the word on Cinavia is getting out and old players are selling
