    CD-Burner Error

    I'm running a MATSHITA cd-burner, and I'll post the log... Someone told me in #gentoo it is related to scsi emulation but on the howto has yet to be written.

    So far I've only been able to burn CD"s in a Fedora installation and I guess that's because they configured my IDE Atapi cdrom correctly with SCSI emulation or whatnot.
    This was done using a rightclick utility in Gnome, so I figured it's nautilus' trying to burn my CD

    Have you tried burning as root? I had a problem similar to this when I switched to udev. Had to add my normal user to the 'disk' group.
