Of CDs, yes. Just put a CD in the drive, and use:
# dd if=/dev/acd0 of=/path/to/your.iso bs=2048

This is possible as the filesystem on the CD is iso9660, and you are just making a direct bit-for-bit copy of it.

But you can't use dd to create an iso of a directory tree on your harddrive.

Once you have a .iso, how do you burn it to a DVD (As just a data disc)? I have tried doing this with burncd and it goes through and does it but i cannot mount the dvd afterwards. I also had no luck with mkisofs burning dvd's with the no-sudo use etc

CDs I can do, DVDs I can't...

For DVDs you need growisofs. There's another chapter in the handbook on DVDs, immediately following the one on CDs.

Sorry, I meant growisofs is what I tried to use. I changed /dev/acd0 permissions to 777, but I get some other error (When using growisofs under a user account). Is it advisable to just burn DVD's as root?

Didn't you get that warning message from growisofs? It doesn't like you using sudo, etc. Look at the man page under NOTES.

I read that before i used growisofs, but I did not have sufficient privileges to do so. All I changed was the permissions on /dev/acd0 but I still received some error to do with permissions.
I did not try running it as root as I have no blank DVDs left. I was asking if I should run growisofs as root to burn DVDs or if there are some simple permission changes I can make to allow me to do it without logging in as root?
