When the drive fails burning
It seems the Panasonic drive has some issues with this media code. Similar to the Philips BD-R DL 50GB discs, these may also fail sometimes. My experience was positive for the most part, but it may still do a bad burn.
While this drive is able to burn these discs, you may get a bad burn every now and then. It seems the drive doesn’t like these discs sometimes, but when it does, it produces a good burn. I’m not sure what may trigger the bad burns, but I guess it may be quality issues and the drive not able to do a proper power calibration. It may also be due to some dark spots in the discs, similar to the spots in the Philips discs. If you’re going to use this drive, keep this in mind.
