Get your original CD, get a DVD-R (not a DVD+R; note the hyphen rather than the plus sign), get a CD copier software (Alcohol 120%, Blindread/Blindwrite, CloneCD) and make a full copy of your original.
I think Warlock is pointing out that older CD/DVD drives, that were designed to read factory pressed CD's/DVD's only, can read DVD-R's much better than DVD+R's. As far as I remember, DVD-R's have similar optical characteristics to factory pressed DVD's than DVD+R's do. (Sorry, if I'm saying something stupid, though...
