Unsupported DVD+RWs

With the NEC DVD+RW ND-2100AD, Imation branded DVD+RWs can not be written. TDK and Verbatim work just fine. The Imation disks are identified as below:

$ dvd+rw-mediainfo /dev/dvd INQUIRY: [_NEC ][DVD+RW ND-2100AD][103D] GET [CURRENT] CONFIGURATION: Mounted Media: 1Ah, DVD+RW GET [CURRENT] PERFORMANCE: Write Performance: 3.9x1385=5408KB/s@[0 -> 1] Speed Descriptor#0: 03/1 R@3.9x1385=5408KB/s W@3.9x1385=5408KB/s Speed Descriptor#1: 03/1 R@2.3x1385=3245KB/s W@2.3x1385=3245KB/s READ DISC INFORMATION: Disc status: blank Number of Sessions: 1 State of Last Session: empty Number of Tracks: 1 READ TRACK INFORMATION[#1]: Track State: blank Track Start Address: 0*2KB Next Writable Address: 0*2KB Free Blocks: 2295104*2KB Track Size: 2295104*2KB READ CAPACITY: 1*2048=2048

A Verbatim DVD+RW delivers the same output except:
