Just picked up the Epson R200 and I need some clarification on printable DVDs. I see where they sell printable DVD and I see some DVDs just labled as "Matte Finish." If a disc isn't marketed as printable, can you still print to it assuming it has a matte finish? The reason I'm asking is because I'd like a silver DVD that I can print to instead of one's with a white finish. Thanks!
