    Ok, lets review the terms:

    DVD-R (the standard ones for superdrives) - 4.7GB
    DVD that you buy at the store (an actual holywood movie) - 8.5GB (already Dual layered
    Dual Layered DVD-R - 8.5GB

    So yes of coures your DVD player can play Dual layered DVD's it already has!
    I am quite sure there are no notebook Dual Layered DVD burners out there yet but if you already have a single layered superdrive it is rumored that you might be able to get a firmware hack somewhere in the future to make it support dual layered. Also you need special Dual Layered discs to burn and those wont be out until later this summer I think and they will retail for $20. So dual layered is nice because you can hold a long movie but is way to expensive if you don't really need that much space.

    It's easy to notice the layer change on a non-progressive scan DVD player when watching a movie. There will be a pause for a brief second or so and then things continue. In Matrix Reloaded happens just after the staircase fight and Neo opens the door to the mountains.

    What does it have to do with whether its a progressive scan DVD player or not? Progressive scan means is displays the lines in order, instead of every other line, like interlaced. Some DVD players might be better at handling the layer change, and some not, but that doesn't mean all progressive scan DVD players handle the layer change flawlessly.

    And for the record, there are not any dual layer DVD-R media, only DVD+R media at the moment, becase the consumer dual layer burners can only burn dual layer on DVD+R

    Hmm I'm wrong you are right but someone showed me a link to dual layered DVD-R and it said that it would be coming out in august maybe it was wrong but anyway to the origional poster that is the idea

    Actually, the chances of your DVD player being able to play them is not very good. See this article that shows that Dual Layer Discs play in only about 60% of DVD Players. That may be improved as the technology matures, but is certainly not encouraging.

    Oh no, you are probably correct, I was just stating that DVD+R DL is here now, and that is what most people are talking about right now. DVD-R Dual layer is probably on the way as you say, but I don't know when, and haven't heard or read anything except for what you mentioned.
