I'm trying to burn some DVD's but when I use mkisofs it thinks that some of my old names are still part of the file name. It lists it as follows.

Filename (Old File Name)

It then insists that the name length is too long and renames them. How do I solve this problems?

Show the command you're using to run mkisofs, and the output.

Also, for DVDs, growisofs (often packaged as "dvd+rw-tools" even though it works on other DVD media) is better than mkisofs.

Well, I spoke too soon. After I burnt the image, all the files were named correctly. I'm not sure what mkisofs was doing. Also, I was encrypting the data, so I had to send the output to my loopback device.

By the way, I asked about making fully encrypted CD's before, but no one had an answer. Well, I figured it out. Please let me know if this helps you.

touch /PathToEncrypted/file.iso
dd if=/dev/urandom of=/PathToEncrypted/file.iso bs=1M count=$size

These two commands make a .iso image filled with random bits. You will need to calculate before hand how large of a .iso file you will need.

losetup -T -e aes256 /dev/loop1 /PathToEncrypted/file.iso

Start your cryptographic loop. The -T option makes it ask for your password twice.

mkisofs -r -v -o /dev/loop1 -graft-points "/=./directory"

This will take all contents in the directory specified (assuming we placed these files in the current working directory) and runs them through the loopback.

mount -t iso9660 -o loop=/dev/loop2 /dev/loop1 /mnt/cdrom

This will mount file.iso. From here you can look through the contents.

umount /mnt/cdrom
losetup -d /dev/loop1

Unmount and kill the encrypted loopback so we can burn without the risk of modifications during the burn process.

growisofs -Z /dev/hdd=file.iso

This will burn the encrypted image. To mount the image do the following

losetup -e aes256 /dev/loop1 /dev/cdrom
mount -t iso9660 /dev/loop1 /mnt/cdrom

It may be complicated, but it is still totally cool.

Probably it was building the translation table for old ISO-9660 drivers that don't understand long filenames. If you were somehow able to mount this disc on a system that didn't support RockRidge extensions you'd see those other (short) names.
