I have no experiences with yout TLA# but I can tell you some other things:
I do not know of any jumper settings to enable SubChannel Data reading. Either your drive or cannot read this data. You should try with a PlayStation game. Use these settings and see if CloneCD accepts them and if the back-up works:
-Read oth SubChannel Data's
-Don't Repair SubChannel Data.
There used to be a problem with Plextools and CloneCD installed at the same time but these problems have been fixed. You can use both programs without any problems.
Hope I've answered some of your questions!
