Recording is refused with a messageDMA speed too slow (OK for 6x). Cannot write at speed 16x.Since growisofs writes at 12x just fine (9.8x overall, 12x outer tracks) clearly there is an issue of some kind with deciding which speed to use, and speeds of >6x as working.Just follow the instructions in the error message.....
Since other software is able to write at higher speed than 6X I'll just use the fastest program available. I thought you might be interested in why it underestimates the DMA capabilities by at least 2x, I wasn't looking for hints on how to make burning take twice as long by running at a lower speed. With a disk plugged into that port I can get sustained write of 43MB/s, so it would appear that the hardware is capable of 16x operation and something is making cdrecord believe otherwise.
