I had purchased LG Laptop model ?XNOTE R405-A. C2D4A2?. This machine has a DVD drive HL-DT-ST DVDRAM GSA-T20N ATA Device. I am receiving alert message whenever I try to play a DVD. On checking in the device manager I discovered that the device is restricted to play only one region DVD. There appears a caution note saying: ?You can change the region a limited number of times. After changes remaining zero, you cannot change the region even if you reinstall Windows or move your DVD drive to a different computer. Changes remaining: 1.? Kindly resolve this problem on priority to enable me to play DVD?s from all region.
