For CloneCD, don't worry about the "Don't repair sub-channel data" box; I never check it. The reason you can't check the box is that the 9100b does NOT write sub-channel data (it reads it). So that means copy protected games won't work via CloneCD burnt via the 9100b.

Back to Nero, I recommend the ASPI layer downloaded from Goldenhawk.com.
