For SD2 - if your burner isn't capable of correct EFM coding then use AWS.
For SD2.51 - don't use AWS as it hasn't been updated to cope with 2.51 yet. Instead patch the image with the modified Betablocker - with a slow read to image file and a slow write.
Sorry - haven't had time to check to see if your drive is capable of SD2 or not.
