Pirates of the Caribbean dont work

I was having a nightmare of a time trying to back up this software using a liteon burner and the latest Alcohol 120%.. Quite a few coasters produced from the first cd....Tried cracks but to no avail..Basically the engine.exe would kick out an error message if original cd wasn;t in...went on Alcohol forums and found a messiah.. Basically it turns out that you read the software with safe disc 2 settings in Alcohol, but when you come to burn it you use standard Safedisc settings, something to do with the efm encoding.....
Oh does anyone know why my cd burner has been upgraded from 1:1 to a 2:1....Slightly mystified by that one....
