I've been trying to burn an iso dvd (video), but when I start it up in k3b, it tells me that I have the wrong medium type. I am using the right type dvd. Here is the exact message:

Thanks for any help.

Try burning on the command line first as root like this:
growisofs -dvd-compat -Z /dev/scd0=/location/and/name/of/dvd.iso

or:
growisofs -dvd-compat -Z /dev/scd0=/location/and/name/of/input/directory

Make sure you are using a new version of dvd+rw-tools and that the medium is formatted first if and only if it is dvd+rw. Only virgin media needs to be formatted, otherwise dvd+rw-tools will reformat it for you initially.

Also, you should use scsi emulation during boot:
append="hdc=ide-scsi"

Let me know if it works.

I added the ide-scsi simulation, but when I put I still get errors. Growisofs output ":-( /dev/hdc: media is not recognized as recordable DVD: 0". I think it's because the drive is in read only (O-RDONLY), but I can't quite figure out what the problem is.

I'm sorry, I didn't realize you were running mandrake! You must take it out of it's automounter control. I would edit /etc/fstab and see if it is ro and contains supermount. Comment out that line and exit. Then, umount the device in question. Now burning should work. What dvd format are you trying to burn? dvd-r[w] dvd+r[w] dvd-ram, or what? That's important.

Try that and let me know.

I killed automount and ro, but am still getting the error. When I try to mount the drive, I get:

Still Read-only. When I now try to get umount the drive, I get:

Okay, it seems that the drive isn't mount at all. Regardless, I go to k3b and try to burn a cd. I get the exact same error meessage as if it were supermount and ro, and I don't think the thing is mount at all! I'm really perplexed here. Thanks for the help.

If you have scsi emulation turned on you can't mount /dev/hdc you must mount like this:
# mount -t iso9660 /dev/scd0 /mnt/cdrom
or:
# mount -t iso9660 /dev/sg0 /mnt/cdrom
or:
# mount -t iso9660 /dev/sda /mnt/cdrom
assuming /mnt/cdrom exists and the cd or dvd contains an iso9660 fs, if not try "-t udf" for video dvds.

Are you trying to mount an empty cd or dvd. Obviously that won't work! I still don't know what type of dvd you are trying to burn, please let me know.

Regardless of what mounting does the following commands should work if
lsmod lists the ide-scsi module in its output:
# growisofs -Z /dev/scd0=/location/and/name/of/dvd.iso
# growisofs -Z /dev/sg0=/location/and/name/of/dvd.iso
# growisofs -Z /dev/sda=/location/and/name/of/dvd.iso

All of them are not found. I'm trying to burn a dvd-r. I've been playing around with all the settings, and can't seem to get any of it working.

Seems like the problem is isolated to hdc too, I'm able to burn regular cds on hdd just fine (it's actually a little slower than usual).

Hmm... It seems that I've been relatively stupid about this the whole time. I never had ide-scsi on, depsite my think I did. So I actually have ito n now, and use /dev/scd0. I tried with supermount and ro; failure. I tried supermount and no ro; failure. I tried no supermount, and now I can't mount it at all, I get permission denied as root.

On bootup, a message comes up saying that it is mounting it as read-only, as well as that it can't read superblock.

Very strange....I was able to burn a regular cd on the dvd drive, but I get medium errors when usinga dvd. I've tried dvd-r and dvd+r, all to no avail. What can I do to fix this up?

I take it it doesn't actually start the burn?
What's the error message exactly?
Is there anything in /var/log/messages or in the output from the dmesg command?
Do you run another OS that you could check out the drive with?

I'm using growisofs 5.17, k3b 0.11, with an MSI DR8-A DVD burner on RH9. So far DVD+RW and CD-RW/CD-R have all worked. This is under RH9 with kernel 2.4.20(RH) and 2.6.3.

The only problem I've had is when the unit was too hot and dmesg reported a tracking servo failure in the middle of a burn - this was after using the drive continuously for an hour including two simulated burns. After it cooled down it was fine.

I was able to fix the problem. I tried burning the dvd from knoppix, which worked. So I then got the newest version of dvd-rw tools and compiled it from source, and then everything worked fine. I guess that the rpm package thar ships with mandrake is messed up.

Thanks for the replies.

The rpm that comes with Mandrake 9.2 for dvd+rw-tools was givin me hell too! I kept getting an error about the write speed being incorrect and it would refuse to burn. I spent 2 days trying to figure it out, finally I downloaded and compiled from source and I was burnin dvds within one minute!

Source rules, rpms suck, I'm moving to Slackware.

Now if only I can figure out how to burn the dvd so it'll play back...

Play back on what?
If you mean a standalone dvd video player then do:
# growisofs -dvd-compat

That command alone won't work, but if you add the -dvd-compat option to growisofs, it should work. Also, some media, dvd+rw I think needs:
# dvd+rw-format -lead-out /dev/your_device
after a burn in order to work!
