Hi all,
I noticed that -tao mode is no longer working on my hardware since
cdrecord-prodvd-2.01b31-i686-pc-linux-gnu
Everything worked fine with a previous version. Here is my system:
P3 933MHz running gentoo (current).

It is not likely to be a hardware/media problem. Both worked before with
following command, but not anymore

It recorded proper, readable DVD+Rs with exactly the same command
on previous versions. Nothing else changed since than (it's running the
same kernel, the same glibc and gcc, and it's still an old session)
