The majority of Sony laptops have a Matsu!!!!a (panasonic) DVD drive.
These WILL NOT be able to be hacked to allow the use of programs like : any dvd, dvd region free, ccs free etc!
It is to do with the RPC1 & 2 setting in the firmware, and as such further "development" to overcome these issue is not being pursued by software"engineers".
Whatever you do,,,, DO NOT change the region settings to anything other than your home region when you only have the last change remaining, otherwise you will be locked into the other region permanently!
