Fedora Users — K3B fails to burn DVD-RW discs

I just got my Optorite DVDRW, drive (12x DVD+R; 8x DVD-R; 4x DVD+-RW; 2.4x DVD+R9; 40x CD-R; 24x CD-RW; 40x CD-ROM; 12x DVD-ROM) drive from Newegg and have just installed it. It is 2ndry IDE Master (/dev/hdc /mnt/cdrom) I also have a Sony 52x CD-ROM, which is 2ndry IDE Slave (/dev/hdd /mnt/cdrom1). I have one TDK 2.4x DVD+RW 4.7GB disc and a 10 pack of Legacy 4x DVD+RW 4.7GB discs, but I am unable to burn on either of them. I checked my fstab file, and the drive automounts CDs fine (in KDE) and I just tested the burner by erasing and then recording a Compaq 650mb CD-RW, which was a success. Maybe this drive is not supported in K3B?

When I click burn, the drive spools up, then I get this error:

:-( Failed to change write speed 0->3324
Failed Error at Startup: Invalid argument
Unable to eject media

============

When I ejected the blank DVD+RW's after the failed burn, they appear to have data written on the inner part of the disc, but K3B doesn't even start the write before it fails. Also, my KDE desktop keeps refreshing as if something is going on in the background, and I am unable to eject the blank disk without rebooting.

Any ideas on how to fix this?
