dd not possible with DVD-ROM drive

I am trying to extract iso-images from CD-ROMs read with a SCSI DVD-ROM
drive. This doesn't work too well, however. I get an error message from dd
about an input/output error.
The drive is /dev/sr0 and the line I try is the following:
dd if=/dev/sr0 of=image.iso bs=2048
The drive works perfectly well in every other respect, both as a CD-ROM
drive and as a DVD-ROM drive, and the command line above works for me on
other systems with a CD-ROM drive, where '/dev/sr0' is replaced with the
correct device.
One thing I have noticed is that the attributes of the device seem to live
their own life. I have tried to set them to user root group disk and set
read- and write-rights for the group, but soon after the device is suddenly
owned by some other user and group is set to users. What gives?
Best regards,
David List
