I have been trying to get the correct behavior but I just cannot manage to do so.

as root:
#cdrecord --scanbus
the following two would be my dvd-burners. One is usb and one is ide.

scsibus5:
	5,0,0	500) 'LITE-ON ' 'DVDRW SOHW-1633S' 'BS0H' Removable CD-ROM
	5,1,0	501) *
	5,2,0	502) *
	5,3,0	503) *
	5,4,0	504) *
	5,5,0	505) *
	5,6,0	506) *
	5,7,0	507) *
scsibus1001:
	1001,0,0 100100) 'HL-DT-ST' 'DVDRRW GWA-4164B' '1.03' Removable CD-ROM
	1001,1,0 100101) *
	1001,2,0 100102) *
	1001,3,0 100103) *
	1001,4,0 100104) *
	1001,5,0 100105) *
	1001,6,0 100106) *
	1001,7,0 100107) *

man says: dev=scsibus,target,lun

#cdrecord -dao -v -gracetime=3 -dev=5,0,0 dvd.iso

so then I only can run this as root. On the other hand there is a Average write speed   7.3x.
Running as user with the old command I only had 2.?x.

Is this normal behavior?
