It of course affects the write speed, if the read spees is too low, then
the speed is limited by the tramsfer speed and not by the readspeed
of the drive.

So you ignore miy advise? Why?
dd does not help.

grosisofs is a very simple program compared to cdrecord.
If the speed is OK with grosisofs, then this only works because
it either ignores the lies from the drive (because it vever asks
the drive) or because it does not check for the DMA speed of the system.
Cdrecord tries to prevent you from writing bad media, but it fo course
allows you to prevent it from artificially limiting you. Did you read the
documentation and follow the advise?
