In the OptiDrive-thread I've got the following answer from DrageMester that may explain some issues:
"The LiteOn iHAP322 doesn't support scanning jitter on CD media, nor does it report all C1 errors (only E31 instead of E11+E21+E31).
I'm not sure about getting the Plextor PX-760 to work with the current Opti Drive Control; it's been a while since I tried that combination and it didn't work for me. I didn't try the "trick" but I wouldn't be interested in using the tool if that's the only way to get it to work.
If you can find a BenQ DW1655/1650/1640/1620 somewhere, then that is the consumer drive, which can scan for the most information on CD media, including jitter on CDs."
You see that the LiteOn drives should supply this OptiDrive jitter reporting with DVDs, at least my model does (and many others, there are separate threads for this). And the Plextor drives 755/760 will do so too, after you've started the Plextools Pi/Po scan and kill it with taskmanager, then drives are in "unprotected" mode and will work with OptiDrive too.
But this jitter-scan works only with DVDs, not with CDs! For this I've bought a BenQ 1620 now and will se if this works.
