Hi guys... I just installed a drivekey in my LU39..I also have the "silver" cable.. I can read my originals, I can access the on chip menu, but get disk read errors on all disks I try. I am using TDK DVD-R's burned at 4x, 1x, 8x...you name the speed and I've tried it! I have been told that I need to jumper X4 to clear this up...any thoughts?
