DMA 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
star is the fastest program... you are missinterpreting messages
I didn't know star could burn DVDs, it doesn't seem to be documented.
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.
I cannot help if your DVD drive is slow or has other deficits that make the
DMA speed test reporting too low numbers. This is not a cdrecord problem
but a problem of your hardware or your OS.
Since the hardware and the OS work at higher speeds with outer software,
it's clear that cdrecord is making an incorrect estimate of the hardware
capabilities. Since you seem uninterested in investigating why that
happens I'll continue using software which can make better estimates of
the hardware.
