Which DVD Players can read DVD-R9s? 1

[DragonQ0105]

Quick question (well, for me ):

Am I right in thinking that all DVD Players that can read DVD-Rs can also read DVD-R9s? I mean if they are able to read SL DVD-Rs, then DL DVD-Rs are exactly the same...but with 2 layers, and all DVD Players can read DL Discs anyway (most commercial DVDs are DL, no?)?

No, a SL player probably will NOT read a dual layer DVD. How can it? Single layer isn't meant to look for or at any other layer. If this were true, then DL or DVD-R9 would have been available a long time ago.

paulrw1,
Good thinking, but it's not true. Dual-layer DVD9 discs have been around for years - not the kind you burn, but the kind you buy (store-bought). Do you remember the early DVD's that came out back in late 1999 and early 2000? Most didn't have that many special features, usually with just a few previews and the movie itself. That's because those were DVD5.

By 2001, DVD9 started hitting mainstream. I remember one of the first ones I saw for sale was "Fight Club", which was packed with a ton of special features. Dual-layer discs made it possible and cheap enough to do. When the DVD spec was first designed, it was designed with DVD9 in mind. All DVD players, including first-generation ones, can read DVD9 discs.

Burners on the other hand are a different beast all together. Store-bought discs are stamped or pressed with the data, they aren't "burned". Making a dual-layer disc as you press each physical layer was easy. However, trying to create a DVDR disc with dual-layer capabilities took a long time to develop. They had to come up with the right material for the bottom layer which had to be both transparent, and yet solid enough to be reliable in storing data. The expense it's taken many companies to finally release DVD9 DVDR's shows in their price. Right now, the average blank disc in a retail store sells for at least $10. When DVD5 DVDR's first came out, they sold for about $7. It won't be too long until DVD9 discs are down to $2 a disc.
