crazy taxi2 copying probs

i can copy most games but crazy taxi2 dont do it using nero. all the files are there but it just wont play. incidentally since reformatting my pc i can only copy at 2 speed whereas i could do 4 speed before with ease. why is this? is it crazytaxi2 that wont copy or is it my crappy freecom external rewriter?

Strange, I converted the USA version to nero, Pal patched it and burnt with no problem on my Phillips..........

##### your drivers for burning speed and see about firmware updating as well.......
