OK. I bought a Pioneer BDR-209D. It seemed to do better than the Optical Quantum BD-R DL discs, but I only had a 50% success rate. Then I ordered Philips BD-R DL discs, and I have been 5 for 5 so far. So in summary: LG WH14NS40 drive and Optical Quantum BD-R DL discs: 0 for 3 Pioneer BDR-209D and Optical Quantum BD-R DL discs: 2 for 4 Pioneer BDR-209D and Philips BR-R DL discs: 5 for 5 (so far) Thanks for the advice!

Thanks for all the feedback. I updated the firmware, but the third try also failed on read during verify. Any suggestions on a drive that is good at writing BD-RE DL media? Again, thanks for the input.

I forgot to mention that this happened twice in a row on two separate BD-R-DL discs.

I see others (e.g., http://forum.imgburn.com/index.php?/topic/24605-bluray-dl-fails-verification-discs-no-good/)are having similar problems writing BD-R-DL discs. I have included the burn log below. Any suggestions?

Thanks much. I will await 2.5.6.0.

Hello, I have a similar problem to one that Gitaroo posted on 01 August 2011 - 12:49 AM: I have a LG BH12LS35, every time when I try to verify a disc I copied, it only read at 2x even though it was burning at 12x speed. And it only does that to dvdr. All the bd-r that I burn verify at max speed. I also tried other program to burn some dvdr and verfy, and they read at max speed. Any idea what is wrong? The difference is my slow verify performance is with bd-r. I can write at up to 10x with Philips 6x bd-r media, but the verify operation for a nearly completely full disc takes about 24 minutes. When I copy the files directly using Windows explorer, the operation only takes about half that time, around 12 minutes. Any ideas???
