The problem I was having with the dmg I downloaded from the url above was it wouldn't boot in my iBook G4. Converting it to ISO format (using PowerISO) then burning it to a double-layer DVD worked for me.
My iBook didn't spit it out and (when holding down the C key upon boot) booted from the damn DVD. Hopefully this will save some people a couple of DL-DVD coasters.

Something to keep in mind, always burn using the lowest possible write speed. Your DVDs will come out better.
