Dual layer DVD-R versus Dual layer DVD+R

Is there a difference between dual layer DVD-R discs and dual layer DVD+R discs? On a related note, is there a difference between dual layer DVD-RW discs and dual layer DVD+RW discs? Is one )-R vs +R, for example) better than the other?

OK, after what I've read in the link, the impression I got is that DVD+R is more reliable than the DVD-R . . . and since my alum Intel iMac is capable of reading adn burning to both, I shouldn't have any problems using a DVD+R. Am I correct?

  • Leopard DVD Dual Layer?

    I read somewhere that the Leopard DVD is a Dual Layer disc. Can anyone confirm this?
    The reason I ask is because Apple just says "DVD drive" which I take to mean "a drive that reads DVD-ROM disks". My G5 iMac has a SuperDrive but my 1.25 GHz 15" G4 Al-PowerBook just has a Combo-drive. I don't think either of these can read Dual Layer disks, or am I mistaken?

    Bad news first... It is certainly a dual layer DVD. Good news... Most commercial DVDs are, and they can be read by any DVD drive! The single layer versus dual layer only comes into play when creating and burning discs, not reading them.
    Just about all DVD movies are dual layer, and have been since the beginning.

    Thanks, Steve.
    I know that DVD hierarchy were originally single-side, single-layer; dual-side, single-layer; single-side, dual-layer; and last dual-side, dual-layer. I didn't know that all DVD drives could read any of these. Of course, I'm ignoring the two HD flavors.

  • Dual Layer Dvds - bad compression, or something worse?

    Hi,
    I've recently been trying to burn a double layer dvd in disk utility but the video seems to have been over compressed into one layer?
    I know my Macbook Pro is capable of doing the dual layer, but I can't find a setting anywhere for it.
    Other cds and dvds will burn ok...
    is it because I'm using a disk image on my hard drive?
    Any help would be appreciated - I've been having a good look around but I can't find anyone with my problem!

    The original post needs clarification to determine what the user meant. Generally speaking, there's data compression at the front-end when encoding information for storage on a video DVD - the conversion of source video into the MPEG2 format. There are two constraints, the permitted bit-rate of DVD video, and the size of the disk. When encoding, the user can specify the size of the target disk. If using iDVD, it won't permit your video to be over 2 hours long.
    One thing to keep in mind is that if the source video is not noticeably higher-than-DVD-quality, the resulting MPEG2 compressed video stream will look noticeably lower quality. For example, if you have MPEG4 video from an AVCHD camcorder, the transcoding to MPEG2 will really degrade the video. None of that has anything to do with dual- versus single-layer disks. Further, Disk Utility doesn't do anything but copy bytes from the image file directly to the disk. It's oblivious to what it is writing and doesn't modify the content or encoding in any way.
    However, in response to the above comment, it should probably be pointed out that the poster lives in Australia, where copyright rules are a little different. Specifically, the user's permitted to make a duplicate of a commercial DVD for a reasonable personal use (backup, copy for the summer house, etc.), the user is also permitted to "format shift" a work (transform it so that it may be replayed on a device that could not display the work as presented on the original). Unlike the USA, an individual can circumvent access controls on the media to do so. Of course, this is limited to fair and reasonable personal uses -- you can't share stuff by P2P or whatnot.
    FWIW - Quite a few legal scholars believe the restrictions the US puts on "accessing" a work are not constitutional. The US' "Digital Millennium Copyright Act" rules regarding access controls (encryption, region coding, etc.) have never been tested in court. I suspect that would fail namely because the US law, as written, also restricts access to works in the public domain (if you've a DVD with a public domain film, but it's encrypted, it's against the law to decrypt it), and because the US has entered into treaties that, among other things, prohibit legal protection on restricting access to works based on their region of origin.
    But, I digress.

  • Backup to DVD doesn't span properly with dual layer media.

    I attempted to use the backup feature in Itunes 7.0.1
    After choosing backup to disc, it provided a warning that the backup would require more than one CD - and that's OK by me, so I went ahead and put media in the drive. It started and after filling the first disk, it stopped and said it was aborting because of an 'unspecified error?'
    My DVD drive is capable of dual layer burning, and I use good quality media. It did successfully burn the DVD, but only part of the library was backed up onto the dual layer DVD I was using. I have used both this drive and this type/brand media succesfully on numerous other projects.
    It looks like the backup routine fails when using dual layer media and backing up more than will fit on one media.
    I could't acess the bug report paga so am posting it here.
    I don't know if it's repeatable, because I don't want to waste any more dual layer DVD's.
    Windows XP Pro, non remarkable system otherwise, P4 2400 - 1G memory no weird startup programs, no anti virus running. pretty much plain vanilla.
    Just thought other might have the same issue.

  • Why won't my Mac recognize Verbatim Dual Layer blank DVDs?

    Why won't my Mac recognize Verbatim Dual Layer blank DVDs?
    I've just completed a 140 minute project in FCP. I've encoded an MPEG2 file that is 5.75GB in size. Brought into DVDSP and am trying to burn the DVD.
    I have Final Cut Studio 1, latest updates and everything.
    Because of the 5.75GB size I need to burn to Dual Layer DVD. I have Verbatim 4x 8.56GB dual layer DVDs.
    When I click buld/burn and pop in a dual layer DVD I get an error saying "please insert compatible disc".
    Even with every app closed. If I put one of these DVDs in my Mac it simply spits it out after about 20 seconds.
    For some reason the Mac won't handle or understand these Dual Layer DVDs.
    I bought this Mac Pro about 4 months ago and it is the 2 x 2.66Ghz Dual Core Intel Xeon machine and the DVD drive (according to system profiler) is a Pioneer DVD-RW DVD-111D. In system profiler it says "Pioneer DVD-RW DVD-111D"
    Can anyone tell me if this DVD player is actually capable of dual layer, or do I need to buy one.
    In System Profiler under Revision it says: AB09 and under Protocol it says: ATAPI
    Can anyone advise please?

    If you have access to a pc into which you can install the 112, or if you have bootcamp, you can replace the Apple supplied firmware with Pioneer firmware. This should restore full functionality to the drive. The latest Pioneer firmware for the drive is version 1.21 and can be found here: http://www.cdrinfo.com/Sections/Firmware/SingleModel.aspx?DriveId=1426

  • DVD Dual Layer Not Working?

    Hi all!
    This is my first time to these forums and I have some trouble with a used Toshiba x205-SLI1 I just bought. the HD Dual Layer burning does not function and the driver appears to be updated properly. It is a TS L802a model, with drivers dated as of 6/21/2006 version # 6.0.6002.18005.
    When I insert the Memorex HD +R Media Nero 9 runs up and begins the process but only goes to about 1% then stops. It ejects the DVD which apears to have nothing written to it by looks since I can put the DVD back in and there are no written areas all i can see with data.
    Plus the speed of the drive only reaches 2.4 when the max is 8X.
    Is there a newer driver somewhere? I need to get this working if possible and without spending tons of money on different media types to "test" the Burner.
    Does this burner have some inate problems as i have read on other forums in burning dual layer dvd's?
    oh, and it does work with the normal 4.7GB DVD's just fine i have done several of these to back up data on the system.
    The system is running as the following drive configuration:
    2 @ 200GB Raid 0. Vista ultimate 64 upgraded from Home Premium by the original owner.
    The Laptop works in everything else and is in pristine condition all over.
    Let me know if more info is needed to make a determination for help please.
    Thanks in advance!

    It sounds like a hardware problem to me.  Your best bet considering it is new is to take it back to the place of purchase and exchange it for a working model (if it's within the exchange period) or contact Toshiba Support and have it repaired under warranty.  Se the Warranty Link at the top of this page for details.
    If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

  • Keeps asking for Dual layer DVD

    I made a slideshow in iMovie and shared to iDVD8. The media windows shows the file as 2.7 gig. But when I go to burn it says to insert a Dual Layer DVD because the project to large.
    I dont have anything else in the project other then the menu which is 3 drop areas. Nothing to it.
    I tried sharing again from imovie and selected medium this time with a files size of 1.7gig and i still get the same thing.
    I do have quality set for PRO.

    good question. I used the Theme that has half the screen as a grey fade. When i added music to it i changed it to 25 secs of playback. I would assume then my menu is only 25sec. It only has 1 button to start the movie.
    At this point I have a DVD+R DL created that works fine my PC. After googling around I read about DL and changing the bitsetting before burning so that a TV DVD Player sees the disk as a DVD-ROM.
    Would I be able to copy this DVD+R DL with Toast 8 and change that setting to make it work?
    BTW, thank you for all the replies.

  • DVD Studio Pro 4 doesn't see my dual layer burner

    Not too long ago, I upgraded my superdrive to the MCE 16X DVD-/+R drive with double layer support. Now, when I try to burn to DVD Studio Pro 4, the drive is not listed as an output option. The only thing listed are my hard drives. Allegedly, this drive is supposed to have native support with both DVD Studio Pro 4 and Tiger. Short of taking out this drive and putting the single layer drive back in, does anyone have a suggestion?
    By the way, it WILL burn CDs in ITunes...

    Don't know much about the burner, but can you can use Toast or Disk Utility as mentioned in may threads involving alternative burning outside of DVDSP?
    If so then there ya go but if not then back to single-layer I guess.

  • Dual layer DVD discs

    I have a few backup discs burned dual layer in OSX with archive material - they read just fine in OSX.
    When I boot into XP via Bootcamp, the discs are not read and are ejected.
    Anyone come across this or got a suggested set of drivers for the DVD drive that will allow the drive to be fully functional in XP ?
    Thanks

    Is it possible the discs were mastered in an HFS only format? In Toast, the default is Mac & PC, but it can be set to Mac Only, in which case the PC wouldn't read them without something like MacDrive for the PC. I had all kinds of problems with MacDrive 7, so I reverted to MacDrive 6.08 in XP.
    If they were burned as UDF, ISO 9660, or from the Mac Finder... they should be readable. I don't think there is anything in the driver that would prevent them from being read other than the format of the disc.

  • DR8-A firware upgrade to dvd dual-layer?

    I am very happy with my DR8-A burner, but i am wondering if MSI has any plans to upgrade the firmware to the future Dual-layer dvd formats.  I have read that Bueq is offer this for their new drives.

    if it can upgrade to 8x8 - good or bad news  

  • G4 DVD Dual Layer question

    I have a 14" G4 1.07GHz iBook with a Non DVD Burning CD/CDR/CDRW/DVD drive. My question is, will it READ a dual layer DVD? Thanks!

    Hhmmm...let me know if it works for you. I have (I think) the exact same setup, and my drive spits out dual discs. We bought Bruce Springsteen's The Seeger Sessions, which is a dual disc, and I had to resort to alternate methods to import the songs into my iTunes library. I Googled after having the problem and found others who had the same problem.

  • DVD dual layer write speed?

    Anybody know what the maximum write speed of the Superdrive is, for dual-layer DVDs?
    I have a late 2011 MacBook Pro 15" and I want to buy some blank DL DVDs.  I'm looking at Verabtim DVD+R DL blank media.  They offer both 2.4X and 8X speeds.  I've read that the 8X disks - which are more expensive, roughly 15 for the price of 20 of the slower disks - can be a problem for older drives that don't support that speed.
    I already know that my Superdrive will write at 8X or more for a single-layer disk.

    "Be sure to take full advantage of:
    About this Mac > ( More Info ) > Disk Burning ..."
    Yup, this showed me that my 8X (single layer) disk could in fact be burned at 8X, but without any DL disks for testing, ATM doesn't tell you anything about burning speeds.
    Thanks for the confirmation that I do NOT want to buy the 8X disks.  I've gone ahead and ordered the 2.4X Verbatim disks.  I also saw some labeled as 2.4-6X, and I suppose those would work with my 4X drive.

  • DVD RW DW-U10A won't read burned Dual Layer DVD

    My friend created a dual layer dvd for me on his PC. I put it in my G5 and after about 15 seconds of the drive trying to read the dist it just gets spit out. It won't mount or anything.
    Why is this happening? I've never had problems reading discs created on a PC. Is my drive incompatible with DVD DL+R media?

    Hi,
    I've been having a similar issues since not long ago. I think it coincides with Apple,s last security update (although I can't swear the 2 are connected).
    I have a dual core 2GHz PowerMac G5 with a Pioneer DVD-R 110D Dual Layer.
    I'm burning Dual Layers medias with Toast 7 (DATA, DVD-VIDEOS ETC). They all mount fine after and I can read the files etc. However if I insert the discs a few day slater, about 50% of them won't mount and are rejected without any error message!
    Anyone else has this problem?

  • DVD dual layer blank media problem

    Hi,
    I used HP branded media without any problems in the past. Now I got a roll of Ritek dual layer DVDs and most unfortunately the drive ejects them as if they were incompatible.
    Does anybody know if Apple keeps a page with compatible media? Or is there any indication which brands would work and which don't? The dual layer media is still quite expensive and I don't know if I can convince the retailer to take back opened disks...
    Best
    Jurgen

    If they're DVD-R DL discs then there's the problem. They should be DVD+R DL.
