CD/DVD Permissions

Question

Okay, i was burning some videos onto a DVD, and after i finished, took the CD out. Now, trying to use the same CD to burn something of the same series, so i wanted to keep it on one CD, i can't seem to copy and paste, delete, or format the CD, and the permissions have been set so that i can only "Acces Files" or something along those line. So im only allowed to view, or play. This happens with every CD i put in. I can put it in once, and change something, but the next time i try to, the permissions have been set to only allow to to "Access Files" and i can't change it as an admin user, or as "su" through the terminal(though i was trying to use the "gksu nautilus" program)

So, sorry if thats too long, but does anyone know why this keeps happening??? And If so, how to resolve this?

Please clarify - what medium type and filesystem are you using, and if applicable, which mastering software? — soulsource, Jul 01 '13 at 14:44

If you want to add files to a recordable or rewritable disc it must have been written in a session mode and that last session must not be closed (see this topic: multisession). Tracks on a disc that are not in packet mode cannot be modified once written.

Otherwise you need to empty the disc and re-burn all the files as a new session (see: How do I format a DVD-RW? ) but this only works for rewritables.

This is not something Ubuntu enforces but how (re)writable media work.

This is not entirely true. Mulitsession can also be used on non-rewritable media. – soulsource Jul 01 '13 at 14:45
