LinuxQuestions.org - unable to burn data dvd...

trying to burn a data dvd without success. using a memorex usb drive. i've tried k3b (which uses growisofs), growisofs directly, and xcdroast (which i think uses cdrecord); none work. here's the growisofs output:

Code:

root@ubuntu:/# growisofs -dvd-compat -speed=1 -Z /dev/sr0=/multimedia/Downloads/track-01.iso

Executing 'builtin_dd if=/multimedia/Downloads/track-01.iso of=/dev/sr0 obs=32k seek=0'

/dev/sr0: "Current Write Speed" is 6.1x1385KBps.

the closest thing i could find on a google search is that it may be related to scsi emulation; don't know if i can get around this using a usb drive? i'm currently running ubuntu breezy on a vanilla 2.6.12-9-386 kernel. i had success burning movies (hadn't tried data) previously; i was using mandriva 2005 with a custom kernel--2.6.14 i believe. any ideas?
