I've just recived some Verbatim DVD-R's with Taiyo Yuden dye from SVP after them being recommended on this forum. I notice they are certified 8X revision 1.0. I bought some Sony DVD-R's the other week that are certified 8X revision 2.0. Does anyone know what the difference means? Does it mean the Sony discs are better in some way? Sorry if the question seems a bit noob-ish.
