[QUOTE=platinumsword;2667101]People have tried to revert back to factory default settings with no success.

My in-laws have a 2007 era Sony that has never been updated and it still works fine.
I am checking eBay and Craig’s list but it looks like the word on Cinavia is getting out and old players are selling
