Would the symptoms of this problem include returning invalid sense codes 
in the event of a problem?  One user of dvd+rw-tools reported that his 
burner was returning a 0xF sense code (which is reserved and presumably 
not actually being set by the device) under 5.x:

brueffer at cheops:~ # growisofs -Z /dev/cd1 -R -J /mnt/disc4/some/files
Executing 'mkisofs -R -J /mnt/disc4/some/files | builtin_dd of=/dev/pass1 
obs=32k seek=0'
[deleted list of files]
/dev/pass1: "Current Write Speed" is 2.0x1385KBps.
:-[ LBA=0h, SENSE KEY=Fh/ASC=FFh/ASCQ=FFh ]
:-[ attempt -blank=full or re-run with -dvd-compat -dvd-compat to engage DAO ]
:-( write failed: Input/output error

Anyway, congratulations on looking into the problem you mentioned above and getting results.  I'll submit a PR to update the port to 5.15.4.8.5.  Happy holidays...
