Who owns, and with what permissions, the devices you're having problems
with. On system the DVD drive (/dev/sr0) is owned by 'root', group owned
by 'disk', and readable/writable by both. The same is true of all disk
devices, whether internal or external. I assume you should see something
similar, since I've done nothing to customise this.
