upgrade dvd repository how to?

[pgmer6809]

I have a dvd with several distros on it (from Linux Fmt Magazine)
I want to use this dvd to upgrade my current version of ubuntu.
how do I tell the upgrade manager to use the cd as a repository/source?
The path to the distro in question is probably something like:
/mnt/cdrom0/xubuntu/dist/oneiric which contains folders main, multiverse, universe etc.

Note this is an UPGRADE not a repository for just updating the current version.

[hbnmgr]

In Synaptic Package Manager, select "SETTINGS" up at the top.

In "OTHER SOFTWARE" tab (must have disk in) and select "ADD VOLUME".

It will then read it, and make sure it is checked in the Other Software window.

Click CLOSE and RELOAD. Look for what you want to install.
