Well, nothing is as easy as it may seem. As I mentioned earlier, I downloaded a copy of Leopard to see if it's worth buying. This download was a so-called .dmg file. This file can be burned to a double layer DVD by the Disk Utility or by using Toast.
The problem is that my MacBook Pro doesn't have a dual layer DVD burner, so I need to burn this one with my external USB NEC burner (which supports burning dual layer DVD's). For some weird reason it (my MacBook Pro) refuses to burn anything dual layer. So in the mean time I'm searching for another version of Leopard (preferably an ISO-file), and I'm using Super Duper! to backup my MBP. Both are taking 'some' time, so I don't think that I'll be upgrading this weekend :-( .
UPDATE: Oke, I found a PDF from Adobe stating that Adobe Lightroom isn't fully compatible yet. So, no upgrade for me. Guess I can stop trying to get the downloaded DMG to work. Well, at least I didn't spend my Sunday on nothing. I figured out how to convert a DMG to ISO.
