Nero burns 16x dvd faster than cdrecord, why?

[bashley]

On the same machine, Nero burns a 16x dvd in 7 minutes while
cdrecord from cdrtools-2.01 takes 10 minutes. I have tried
3 different brands of disk, updated the firmware on a Pioneer
110, but cdrecord consistently burns a 16x in longer time than
it does an 8x.

Do dvdrecord or Prodvd handle 16x blanks correctly?

TIA

cdrecord can't burn DVDs. I'd also stay away from cdrecord-ProDVD. I recommend dvd+-rw-tools for burning DVDs.
growisofs -dvd-compat -Z /dev/dvdrw -dvd-video <DVDDIR>

Another vote here for growisofs

The speed control switch is, intuitively enough:


-speed=4


and you can use input from a disk image, or the mkisofs options
like fs types, Volume Names, etc.

Thanks for the suggestion. Using:

growisofs -dvd-compat -Z /dev/dvd=image.iso

I achieve the same burn speed as Nero, 6min8sec.
