DVD+R vs DVD-R: Any issues with disk copying?

Discussion in 'DVD Video' started by (PeteCresswell), Feb 19, 2006.

  1. Somewhere along the line, I wound up with a stack of each type of disk.

    Been burning to DVD+R, and now that stack is depleted. No problems
    so far with the media type.

    I'd like to delete the .ISO files that I used to burn those discs.

    Question: Will I have any problems if/when I just do a disk copy
    from a +R disk to a -R disk?

    You may lose some compatility with old players. But if that is the
    case, you need to upgrade anyway.

    DVD-R is *more* compatible with old players than DVD+R. So in that
    respect, he won't lose anything by copying something to DVD-R.

    To the OP, no, you'll be fine; the disc capacity is the same.

    You are overlooking the capability to bitset +Rs. Then they become
    totally compatible. You cannot bitset -Rs.

    Don't leave out bitsetting from your considerations.

    What? DVD-R and DVD-RW are the official writable and rewritable
    formats from the DVD Forum. They do not require bitsetting to comply
    with the standards.

    Bitsetting was/is a kludge only necessary for the +R format.

    Pete,

    My "for dummies" (I'm certainly no expert) explanation is that
    bitsetting (finalizing) a DVD+R recordable makes it "look" like a DVD
    ROM (ie, "pressed" or commercial DVD) to the player. I'm sure someone
    will correct me if my understanding is wrong.

    If somebody had to choose between a spindle of -R and +R blank DVDs, which would
    be the logical choice, then?

    Sounds like +R... ?

    Absolutely not. Assuming your burner can do both (as mine can), I'd
    buy DVD-R (as I do). The only reason I'd use DVD+R for video is if I
    were using one of the home video recorders, because it doesn't need
    finalizing the way DVD-R does.

    But when it comes to burning stuff from a computer, that "advantage"
    becomes a liability in terms of compatibility with regular DVD players.
    As Oldus Fartus pointed out, the "bitsetting" is simply a kludge to
    make DVD+R somewhat more compatible. DVD-R is more compatible right
    out of the box.

    For me, yes +R is the choice.... BUT it's because my stand-alone DVD
    recorder (ILO) uses "only" +R DVD blanks, and my in-computer burner
    will burn either. So it's convenient to keep only one kind on hand. If
    I had a different stand-alone that took only -R blanks, I'd simply use
    -R instead. IOW, other factors often make the choice.... either type
    works fine in most players.

    Did you read what I wrote?

    I said that bitsetting was for +R.

    +R discs have a place on them to designate the type of disc.
    Bitsetting is a way to make the disc look like DVD-ROM, which is
    highly compatible.

    There are some incorrect statements on the earlier replies in this
    thread, but I do not have time to correct them.

    It's widely thought that it's impossible to bitset -Rs as information on -R
    bitsetting is not widely circulated.

    The reality is that if you know what you're doing you CAN bitset -Rs but
    those in the know also know why there's no point in doing so.

    The bitsetting trick doesn't necessarily work with all DVD players.

    Furthermore it's used to compensate for +R compatibility issues that -Rs
    simply don't suffer from in the first place.

    The reasons for this are purely historical and relate to the fact that -Rs
    got there first but this is somewhat academic now.

    The fact of the matter is that -Rs are inherently more compatible with older
    stand alone players.

    Yep, works great. But my DVD-recorder (a DVD+R recorder) still
    recognize a finalized DVD+R with booktype DVD-ROM as a DVD+R, so it's
    not 100% (or does the recorder look at other things than booktype).

    Yes. A drive that completely groks +R/RW will always be able to tell
    what type of disk it really is. It's the drives that technically only
    understand -ROM at best that bitsetting helps with. Some of these -ROM
    drives also do a good job with -R/RW because the format is so close to
    -ROM, but others do not.

    To be honest, the format isn't as much of an issue as the disk
    reflectivity. Pressed disks are highest, followed by ±R, followed
    by ±RW. This is why many drives have problems with burned disks, and
    re-writables in particular.

    Indeed you did, and to repeat, you said "You are overlooking the
    capability to bitset +Rs. Then they become totally compatible. You
    cannot bitset -Rs." which to me at least, suggests that bitsetting is
    something which gives the + format an advantage over the - format.

    Contrary to your opinion DVD +R do not become totally compatible because
    of the kludge, because not all players are fooled by it.

    For my own use I have no preference to which format I use, but I have
    learned the hard way when transferring video to DVD for customers, that
    the -R format offers the most compatibility with *most* of the players
    out there. This is improving all the time though, and as older players
    are replaced, compatibility becomes better.

    Bitsetting tells the player that the disc is DVD-ROM, which is
    compatible with all standard players, old and new.

    But you did not employ bitsetting on the DVDs.
