Don't forget that pcd and pg cannot be used at the same time in 2.0

It's hard to tell from the information we have so far. Please start by
loading pg with the verbose=1 (or even verbose=2) options so we can see
a bit more of what is going on.

I recommend using cdrecord 1.6.1 and building it to support pg.

Make sure that /dev/pg0 exists and has the correct major and minor numbers.

Unless your port is flaky and you are not getting reliable communication
with the drive. Enabling verbose logging should answer that question.

That's irrelevant and unnecessary.

Also unnecessary.
