(a > slightly newer but still not dual-layer drive) Were they guessing, or had they checked? It'd be easy enough to check. The only reason I could see for them using dual layer, where it wasn't needed, would be getting a good deal on the pricing. For what it's worth, all DVD players (including computer ones) can read dual-layer. It's been in the specs since the beginning, and required of them. That's not to say that some particular discs could be sub-standard, and don't work well in some drives. It's just that, until recently, most burners couldn't write to dual-layer discs. That's something quite different than reading them. -- (Currently testing FC5, but still running FC4, if that's important.) Don't send private replies to my address, the mailbox is ignored.
