Hi, the answer is the following: Plextools Professional. However, while Kprobe works on practically any Liteon Burner, only a few Plextor drives have quality check capabilities. :sad:
To be more precise, the Plextor Premium CD-Rewriter (aka 523252) is able to perform C1/C2/CU test and beta/jitter test. I have it, use it for testing CDs and it works well.
About DVDs, the brand new Plextor PX-712A DVD-Rewriter should be able to do PI/PO quality checks with DVDs... However, it is not yet available here in Italy so I can't tell you more than this.
