Curious???? Why would you even want to use dvd media for a cd based game? That dont make sence to me

The cost for the 2 types of media are significantly different. DVD-R's are much more than CD-R's. This is why most would seem

as to why anyone would want to spend more than necessary to make a backup.
I wonder if your problem could be more of a laser issue if it is having problems reading cd-r's.
