Hi! I have a LG UH12NS30 in a PC running Win7. I wanted to use DiscSpeed to test some BD-Rs. It correctly identifies them as CMCMAGBA5 under Disc Info. But all test options (xfer rate, create data disc, etc.) are grayed out. I had also tried Speed 4.11 with same result. At least I could create and check a DVD-R. Is there something needed to unlock the BD-R capability? Thank you!
