Comment 5 for bug 146682

Changing the device permissions is no option as it just introduces
unneeded security problems.

There is a conceptional bug in wodim that is causing the problems:
The people behind wodim did remove checks for the needed privileges
in the code. As a result, wodim is faling later with unspecific problems.
In order to be able to send all needed SCSI commsnds for CD/DVD/BD
writing, a software needs to have root privileges. Ignoring this fact causes
problems.

The original cdrtools installs cdrecord/cdda2wav/readcd suid root and this
is why the problem described in this bug report does not apply to cdrecord.

The best solution is to upgrade to recent original software from

ftp://ftp.berlios.de/pub/cdrecord/alpha/

compile and install (the latter as root).
