CD-R or can i use a CD-RW???

[quadman]

trying to copy medal of honor,using cloan cd 4.0.1.6 does it make a difference if i use a cd-r or a cd-rw. id like to use a cd-rw till i know its going to work,then write with a cd-r. so far it will copy the disk but when you try to use it , it seems like its trying to start and slows down,and tries to start again off and on like that till it quits. any help is welcomed,thanks quadman
