OSX disc burning

Ok so i have the Operating System discs for 10.4. A few weeks ago i lost them at my friends house and didn't find it til a few days ago. I was really worried because thats everything! I wanted to prevent that from happening by burning a backup. So i made a disk image from the original disc and noticed that it would highlight the option to burn. Its not a burnable cd is it? If not im putting it in a safe lol. Thanks all.

You can make a copy. Pop it in, drag the icon to Disk Utility left hand pane, eject disk, pop in blank CD, and burn.

Yea i did all of that but the button to click "Burn" is not selectable. DVD is blank, the disc image is clean and free of errors but it still wont let me do it.

How do i make my profile reflect what i have on my system?

erm...

I have no idea why it isn't working but maybe let the open source Burn have a go

Burn - Home
edit: in the top forum buttons, select profile - you can fill in any details there

I had the open source burn but it would always close with an error report and never work. I have a thread about that too actually lol
