|You can read a CD in a DVD drive but you cannot read a DVD in a CD drive.|
It is the storage difference that makes all the difference. Becasue there is more data on a DVD drive, the tracks are a lot closer together and the data is more closely packed. To read this data a different kind of laser is required, a finer more precise and a higher frequency laser. Consequently a CD laser will not do anything to a DVD disk, it is far to course.
No amount of software is going to change what is in fact a physical limitation.
