that isn't a "hard" to copy cd according to the skulls but if it is unknown i always use the burning program Alcohol 120%.

The best thing you can do is to make a image and then load it into your image drive (virtual cd drive),
at this way you wont spill any cd's and can try time after time without any problems.

The setting i use for a unknown game cd in Alcohol are:

1 - Skip reading errors
2 - Fast skip error blocks
3 - Read Subchannel data from current disc

goodluck.

I'm looking on some other forums for you if this problem is well known.
