I'm having the same problem. The os is redhat linux 9. I was using version cdrecord-prodvd-2.01a27-i686-pc-linux-gnu until the binary expired.
I tried downloading cdrecord-prodvd-2.01.01-i686-pc-linux-gnu (and also cdrecord-prodvd-2.01b31-pc-linux-gnu and cdrecord-prodvd-2.01-pre-i686-pc-linux-gnu) but they now report that the tao write mode is not supported by the device even though it used to work:
Message I get now:

Why did it change? Should I just use -dao ?
