Copying a 1:1 version of Warcraft 3....?

[Shadovv]

I've don't know if this is will be of any help to anyone, but I noticed when trying to copy wc3, it won't let me read the CD at 1x, it jsut jump's to 4x. (this is using Clone CD 4)
And the write speeds shouldn't matter does it?....(correct me if I'm wrong)
I mean as long as you can get a good image to burn from, the result of what speed you burn at should affect the outcome. should it?
