I have been trying to burn Memorex 16x MBIPG101-R05 disks with a BenQ 1640 and bsrb firmware. These are DVD+R disks, purple wrapper, older, silver disks with the little decorative squares. Scans in the forum indicated that excellent burns of MBIPG101-R05 are possible with the correct burner. I have over 200 of these disks sitting in my closet, so I thought I could find a way to make them useful, but something is wrong.
With the BenQ, the best burn so far, has been a 70. Other burns were 50, and below, even 0. So I ran Qsuite v2.1 on several disks, and the application doesn’t recommend burning these Memorex disks at any speed ( I tried every speed test ). Somehow, I don’t think the application recognized the media. During a 2.4x speed test, the media was declared “unknown”. MediaCodeSpeedEdit clearly lists the MBIPG101-R05 media code in the bsrb firmware, and I have snapshots of good burns that were posted in the forum (burned & scanned with a BenQ 1640). I was sure my approach to this was bullet-proof.
Could the manufacturer have made an error with the MID ? Is it possible that this media is not MBIPG101-R05 ?
I have other burners… using a NEC 3500A burner and firmware 2.TG, I burned a disk with a quality score of 82. That is the best I can do. I have tried 3 -4 firmwares on 3 -4 different burners. I also used SolidBurn & WOPC with the BenQ 1640, but learning mode had no effect. In fact, I think I burned a 0. Sidenote; depending on burn speed used, I boot win98 or XP, but this has had no effect on the results.
There is no discoloration on the recording side of these disks. They are sturdy disks, I see nothing wrong… Any ideas ?
