    Is there any difference between Regular, and Dual layer Discs besides capicity? I was just wondering if a Dual Layer disc will work in a regular DVD player, that plays regular discs fine, or does the player have to support something special to use Dual Layer discs?

    FWIW many movies ship on DL discs... every once in a while a disc has a visible layer change pause in it.

    The question is when are Dual Layers coming out for consumers to use. I would be gleaming to get some of those disc for backup of my stuff. But I think they are not releasing it for piracy issues like thats helping to stop bootlegging movies.

    Anyway good luck finding dual layer DVDs if you can find them at a good price.

    Wait, what is it that you want that isn't available? Are you talking about hook-to-TV DVD recorders? Granted DL media is not super cheap, but they are fairly readily available....

    Google search for 9gb DVD-R's or DVD DL and bingo you have tons of options all fairly cheap.

    I think theWholeTruth answered the question...let's break it down.

    You get double the capacity with a Dual Layer Disc.

    They should work fine. If in doubt do a test.
    As mkrishnan said "FWIW many movies ship on DL discs... every once in a while a disc has a visible layer change pause in it."

    It's just that the consumer DVD burners couldn't burn Dual Layer.

    DL DVD Recorders

    Dual Layer DVD recorders are available from Panasonic and Pioneer at least. The DL DVD isn't quite double the single layer DVD (8.5 Gig as opposed to 4.7 Gig). From reading the manuals on line, you can only record the first layer, then close that layer, then you can record on the second, after that you have to close and finalize the entire disc.

    So, you can't quite record 2 hours per layer because each layer has less than a single layer. You can use a sort of fit to disc for each layer so that you get the 2 hours/layer, but you start to decrease the quality.

    The computer drives you can just record on and the recording goes across the 2 layers...
