I've been making some data DVD coasters and now I'm looking for help on successfully burning data DVDs. Currently I'm running RedHat 9.0 on an Asus A7V333 motherboard. It has an AMD Athlon XP 1800+ processor and 512 MB RAM. I bought a Sony DRU-510A DVD/CD Drive. It claims to be able to read/write: DVD+RW 4X, DVD-RW 2X, DVD+R 4X, DVD-R 4X, DVD-ROM 12X CD-RW 16X, CD-R 24X, CD-ROM 32X The Sony drive will mount CD-ROMs with no problem, both the ones I have created and a few that came with various books. I used the following command to create the test data for both the CD burn test and the DVD burn test. mkisofs -R -o pdf.raw /home/tlittle/pdf/ I've had no problem with using the following command to create data CDs using imation CD-R media. cdrecord -v speed=4 dev=0,0,0 -isosize pdf.raw It can also burn audio CDs that work in my home stereo and my car stereo. cdrecord -v speed=4 dev=0,0,0 -audio song-title.wav I've tried to burn data DVDs using Memorex DVD+R media, imation DVD+R media, and imation DVD-R media. All with no result. dvdrecord --scanbus gives back this result: [root at localhost root]# dvdrecord --scanbus dvdrtools v0.1.3 Portions (c) 2002 Red Hat, Inc.
