.. I have the LG external burner BD-RE BE12LU30 and could initially describe the DL 50GB blank problems and play on a PS3. After only 4 playing options of the burner could describe the blank only very slowly, the PS3 is no longer recognized him. An exchange of the blank in a new yielded unfortunately the same result. Meanwhile, no longer even recognizes the burner the blank, format it can not be also. At the OS (Vista 32 bit) or the firmware does not seem to lie. When burning program came several used, among other things ImgBurn with detailed log. Can not therefore recommend the blank.
