However, good though EAC is, I have a mounting list of CDs where one or two tracks just simply won't rip, even after the T-Cut treatment.
Sometimes it's the drive being used - have you tried installing EAC on another machine and ripping the CDs ?

I have both a DVDRW and CDRW in my machine, and occasionally have trouble with a disc not ripping securely in one drive, but for some reason the other will.
I'd almost put money on the discs not complying to red book standard, hence the issue.
