Thanx for the explanation.
So, I tried
$ wodim -v dev=/dev/sr0 speed=4 image6.iso
. . . .
Speed set to 1764 KB/s
Starting to write CD/DVD at speed  10.0 in real force TAO mode for 
single session.

I interrupted the burn, as it did not obey 4x speed.

So, I tried 6X.

$ wodim -v dev=/dev/sr0 speed=6 image3.iso

Speed set to 1764 KB/s
Starting to write CD/DVD at speed  10.0 in real TAO mode for single session.

When I add driveropts=forcespeed, it still says:

I believe that wodim may be the source of the problem.
