Buffer overruns are *not* denoted with "INVALID ADDRESS FOR WRITE," and
should be handled by application transparently. *Unhandled* buffer
underruns in turn *are* denoted as depicted in originating post. How do
you come to the conclusion that it's overrun condition?

If your system is subject to buffer underruns, another recording stategy
might do the trick as well. As previously mentioned, buffer underrun
protection appears to be optional for the recording strategy supported
by cdrecord-ProDVD, namely DAO. growisofs on the other hand defaults to
Incremental recording, where buffer underrun is mandatory: "If BUFE bit
is set to 1 [and] the logical unit detects buffer under-run, the logical
unit *shall* perform the Lossless-Link." As for using DVD+ instead.
Buffer underrun protection is unconditionally on (can't be switched off)
in all DVD+ recordings.
Yet it should be noted that the reported error condition is rather
unusual. As mentioned above it appears as buffer *underrun* condition,
but the catch is that underrun condition at the reported LBA is hadly
possible... It either have everything to do with the recording strategy
(try growisofs) or that particular media brand support by unit firmware
(try another media brand). And *if* it's external unit, there is a
*remote* possibility that it's subject to special condition observed
unser Solaris 8. A.
