Can't seem to copy psx games anymore

[Moose]

Did psx change something in their way of making the newer games. I have copied several in the past and then stopped for awhile and just recently started again and just can't do it. I have done everything the same as in the past and nothing happens. Cdrwin says it copied successfully and it looks like the disc has something burned on it and yet nothing on psx, tried to see what is on disc on computer and it says to insert disc. What's up with that??
