I am not sure if I understand you the right way, but the facts are:
- On previous Linux versions, it was possible to make cdrecord
work without root-privs in case you did compromize security
on that system and in case you did not care about coasters
or write quality.
- With Linux 2.6.x, it is impossible to run cdrecord without
root provs.
Do not believe single persons who claim otherwise as Linux-2.6.x
filters away random SCSI commands when cdrecord does not have
root-privs and as cdrecord heavily depends on the fact that
the SCSI protocol depends on SCSI commands that "fail" because
they are not supported by the actual drive in order to correctly
support the features of the actual drive.
It is definitely impossible to support "correct" DVD writing
without having root-privs.
- Recent cdrecord versions (see ftp://ftp.berlios.de/pub/cdrecord/alpha)
include workarounds for the incompatible interface changes on
recent Linux versions and allow you to use cdrecord in case it
has been installed suid-root.
- The "latest" cdrecord version on Debian is definitely broken.
My suggestion is:
- get a recent copy of the original cdrtools source from
ftp://ftp.berlios.de/pub/cdrecord/alpha
and compile it.
- Install the cdrecord/cdda2wav/readcd binaries suid root.
