you can try that too, or iboot vostro, you should download these three (that is like a russian roullete)

Could there be a problem with how I burned the DVD or my computer set up?

Also, I am running low on CD's so can I use DVD's for the cdboot's?

yes, you can, maybe it can be you image burned

How other way should I try to burn it? Because the same issue happened with NawCom and iBoot

burn with the minimal speed, with a good burner

I did.. what about converting the image to a iso?

isn't it a iso? you can conver if it is not, no problems

No, it's a dmg file.

Same problem when I convert it to an iso and burn it....

than if it it's gettin hard, i would try to instal in a external driver in a desktop, after you have osx with the minimal function, and booting into your notebook, will me easy
