Thanks for the replies. The drive has finally arrived and I've just installed it. Its a standard OEM drive, looks like nothing fancy at all, doesn't even have Benq on the bezel, just on the silver label!
Using the Nero Info Tool, the firmware is G7H9 ad the read and write speeds are 8x. Shouldn't they be 16x? Is it worth flashing to anything else?
First burn was a coaster! I'm using Infinity DVD+R 8x media. Nero has detected the Manufacturer ID as CMC MAG E01. What does that tell me? :a
Trying another burn now and will report back.
