    I see that dual layre DVD writers are out there now & so are the discs.
    Does anyone know if these are available in any other format than just "+"
    type ??

    Not sure as yet -- but just wait a while - prices for the individual disks
    is high right now -- but will fall very quickly - so basically i am
    saying just be patient

  3. as far as i can tell only + is available in dual layer at the moment.
    lynxdv certainly aren't stocking any other dual layer disks.
    there are no dual layer dvd-ram cartridges , they are dual sided , and
    yes you have to turn them over in e50's and e55 panasonic
    there may be a drive out there that can write to both sides without
    turning it over.

    No, that's why they're called dual-layer, not dual-sided.

    And I'd also add that, from what I've read in more than one magazine,
    they're a whole lot less compatible with standard DVD players than the
    manufacturers would have you to believe. Seems to me to be a bit half-
    baked at the moment and not worth the time nor money, as yet.

    The question is, will they get the technology right before Blueray takes
    over and makes them redundant anyway?

  6. no , they are dual layer , both layers on one side of the disk.

  7. one solution is to set the bit-setting to dvd-rom , which then seems
    to get over some problems in some dvd playback decks.

  8. Dual-layer are single-sided, high capacity. We've also been informed
    that double-sided disks are available. Presumably each side is
    single-layer, though presumably a double-sided dual-layer disk is

  9. The market is for copying commercial video DVDs at original quality.

    I'm not sure if the makers are currently one jump ahead in the
    copy-protection game, or one jump behind :) But if you can play
    media, there's generally a way to copy it.

    errm... no they're not. Name some releases that have been 2-dvdr? No
    actual scene group releases will be, because they know how to reencode
    dvds properly. No two-click solutions here. They use multipass CCE
    encodes. I know that's outwith the capability or means of most home
    users, but unless you're using uncompressed PCM audio, you should get
    two hours on a dvdr no problem.

    A lot of movies are ripped to two svcds or two xvid+ac3 discs, but not
    two dvdrs. Two dvdrs would be un-recompressed, with nothing ripped out.
    It'd be a bit silly to spend a whole day downloading 9gb for one film,
    would it not? Now, if it was a dvdr9 release, which are starting to
    appear now...

    Er, isn't that exactly what he said with regards to Disney's Robin Hood,
    or did I miss something?


    Mark A, Oct 11, 2004

    Mark A Guest

    But he pointed out that Disney's Robin Hood, as is, is smaller than the
    capacity of a DVD-R. Therefore a DVD-R copy of it would be identical as
    there is no re-coding going on.

    Now, had you said that the moment any re-coding is called for then there
    must be some sort of degradation going on, then that would be a
    differenat matter, but that's not what you said, and not what I
    pointed out.

    Judging others by your own standards *again*.

    It is? Let me quote you: "In case it's too difficult, the assertion was
    that you can squeeze a full commercial movie on a DVD-R or DVD+R without
    a loss of quality". Which is 100% wrong in the case of these Disney
    DVDs. Plus any other films which fall under the 4.7Gb limit.

    You can't expect people to know that you meant "Except in the case of
    films that are small enough to fit on one disc" from your rather bilious
    posts. You repeatedly made this sweeping generalisation, the one above
    merely the latest. As such, you were, and still are, utterly wrong, and
    trying to wriggle out of it by limply implying "but, it's not what I
    meant" is simply pathetic.

    You can easily acheieve that, removing the extras and extra audio
    streams is a start, then beyond that it's a simple case of

    To be honest i've seen 90min 1GB XVID movies that are not severly
    lacking in quality.

    I guess it all depends on the TV and player, i.e. the better the
    equipment the more artifacts will show.

    Urmm.. Surely this is illegal?

    Isn't the reason that DVD's are over the single DVD-R limit to prevent
    easy piracy? I don't think quality is really the issue.

    This from someone who gets much of what he says technically wrong and
    then either insists he's right, despite all the evidence, or then claims
    he never meant what he said. And when all else fails, rounds out his
    charming repertoire of bluster and bull with personal insults. What a
    Oh no, how will I sleep tonight?

    There's the audio to add as well, but you'll not be adding DTS ;)

    What the HELL has mpeg-3 got to do with this? Tony, you astound me with
    your stupidity. Every post you make, you get dumber.
    It's not pompous, they just know what they're doing.
    And you don't, as proven here. A simple google for CCE would've given
    you the answer on the first page, and the result would've been higher if
    you'd included "encode" or something, no doubt.
    Errm... Those are all toys. They're perfectly good for someone who knows
    nothing about what they're doing, but for someone who cares, someone
    interested in the quality, you just don't use 'em. There's your problem
    straight away.
    I can't speak for your friends, but you definitely know far less that
    you'd like (us) to believe. I brought up xvid because you were talking
    about things being on 2 discs and in decent quality. I was thinking
    maybe you'd made a mistake, rather than you were thick. Seems i was
    wrong to give you the get-out clause.

    Get over to www.vcdquality and look at some of the dvd releases there.
    These are GENERALLY released by people who know what they're doing. Now,
    get onto your P2P apps, and download some of the vob samples. Tell me
    these aren't good quality...
