We have been using v2.20 for about 2 weeks and have sucessfully copied 130 or so discs. For some unknown reason today, it is failing to completely copy the discs, ejecting them after 2 or 3 songs. All settings and drivers have been rechecked and appear to be set properly. This has happened with 3 different source discs. We have sent the dxdiag file to you. Thanks in advance for your help.

Problem Fixed by Reboot
 

After much thought, we realized that we had tried everything EXCEPT the one thing that is the easiest and probably should have been tried first....REBOOT!!

After a restart, we have sucessfully copied 15 discs. So....problem solved for the meantime. No need to strain the tech support brain, at least right now. We'll post again if there are any more problems.
