not work very well on some CD like windows98 :-) 2 unused tracks or so
get copied from CD. See following memo on how I did.

This is documented somewhere in cdrecord documents.

Above method should avoid this.
BTW, if in doubts, always use command line tools like cdrecord which is
actually backend of cdroast. There is rich documentation and special
options.
