On a system with a SCSI DVD-ROM drive and an IDE CD-RW drive I try to burn 
from the DVD-ROM drive directly to the CD-RW drive. With no luck.

I am trying to do the same thing that works on other systems with the same 
setup: find the the burner drive with 'cdrecord -scanbus' and insert it 
into the line
cdrecord -v [burner-drive] speed=1 -isosize [source-drive]

On this system it becomes
cdrecord -v dev=2,0,0 speed=1 -isosize /dev/sr0

I cannot do this as a regular user on this system. The message is:
david@dt:~> cdrecord -v speed=4 dev=2,0 -isosize /dev/sr0

If I su to root and issue the same command, the usual startup-messages 
appear, but no real burning takes place when it should start. I just see 
this message:
Waiting for reader process to fill input buffer...
And the source-drive spins up and down forever.

Burning from ISO-images to the CD-RW drive works fine.

What could the problem be?

TIA
