ufs and Plextor PX-708A 1.04

I'm running 4.9-stable from November.
I've recently installed a Plextor PX-708A v1.04 DVD rewriter. I'm
getting good results using growisofs.
On the belief that +RW support random access, for a bit of fun I created
a ufs filesystem on the device with freshly formatted DVD+RW media:
disklabel -r -w cd0c auto
mount -o noatime /dev/cd0c /mnt
On the face of it, the mounted filesystem then appears to work. However,
intermittently (within minutes, but after several MBs), read errors
>(cd0:ata1:0:0:0): READ(10). CDB: 28 0 0 1 65 a8 0 0 20 0
>(cd0:ata1:0:0:0): MEDIUM ERROR info:465b0 asc:11,5
>(cd0:ata1:0:0:0): L-EC uncorrectable error
>(cd0:ata1:0:0:0): cddone: got error 0x5 back
I'm probably being hopelessly ignorant. Should this work? I believe
the drive supports DVD+MRW (Mt. Rainier), and that this is supposed to
implement some sort of defect management. However, is OS support
required as well?
Any advise appreciated.
