I am once again looking for blank media, and I have seen some discrepancies that concern me. Cases in point; 1. Verbatim has two types of DVD-RW media for sale. One is rated for 1x-2x, and the other is 2x-4x. 2. The Ritek 4x DVD-RW is getting horrible ratings on Amazon, mostly from people with Pioneer A03 -> A05 burners. My question is: Has anyone with a Superdrive models A03 -> A06 tried any of the newer 4x DVD-RW media, and what has been your experience? Max.
