How can I prove this with -prcap if -prcap gives me the wrong values ?
I can prove it with growisofs:

newdeal:/pub/temp# growisofs -speed=8 -Z /dev/hdc=data.iso
Executing 'builtin_dd if=data.iso of=/dev/hdc obs=32k seek=0'
/dev/hdc: "Current Write Speed" is 8.2x1385KBps.

while 

newdeal:/pub/temp# cdrecord-dvd -dev=/dev/hdc -speed=8 -sao -data
data.iso -v

Yes, the drive was empty.
Now this is the output of -atip and -prcap with a certified 8x dvd-r
media inserted.
