    I've backed up hundreds of DVD's - always used DVD+R's - all MID YUDEN000 T02, mostly Fujifilm's. Until recently, all had been bit set to DVD-ROM, as my burner has this feature. Although I have a 16X burner, all were burned at 8x. I always shut down all other processes while burning, including virus checkers, etc.

    A percentage (10%?) of these discs will occasionally pause momentarily during playback on my Sony (fairly new) standalone. Friends have borrowed my back-ups and report the same thing with different brand players, although, most also have Sony. Pauses never occur more than 2-3 times during a movie, and never in the same place.

    Makes me wonder if changing the book-type to DVD-ROM, instead of leaving at +R, could be a mistake. Anyone know if it is possible that, by tricking my set-top player into thinking the disc is DVD-ROM, that I could be defeating some kind of read strategy the player may have for +R discs?

    Recently, I stopped bitsetting to ROM, and am leaving them at +R. For good measure, I've also slowed down my burn process to 4X. I have not noticed this momentary freeze on any of these, however, I have not burned anywhere near the quantity at +R that I have ROM, so I really cannot draw my own conclusion just yet.

    Just curious - anyone think there could be something to the notion that bitsetting to DVD-ROM could be contributing to these momentary freezes (by defeating what might be a beneficial +R read stratetgy), or is the cause more likely a player's fussyness with burned media, occasional "less than perfect" media, or any one of a number of other variables in the backup creation process?

    It's probably more related to burning at 4X than bitsetting. Bitsetting is just that, one bit telling it what type of disc it is. Especially if they played fine inititally, it is much more likely to be media related (everything you mention in your last paragraph) than due to the bitsetting.

    The only other thing I can think of is MAYBE your players slightly change their calibration based on thinking they're reading "DVD-ROM" instead of +R discs-- i.e., maybe they compensate for the lower reflectivity, providing better reading quality. I've never heard of anything like that, though.

    Could DVD-ROM bitsetting be a bad thing?
    No

    Sony players are picky. Easy as that.

    I have also had problems with intermittent pauses in some of my backups, with the player never seeming to pause in quite the same location twice. I have found the problem, at least in my case, is simply the power supply. The electricity in the area I live is uneven at best, and it seems this problem shows up with recordables more than it does pressed discs. Although I have also had pressed discs pause like this too, which should tell you something about the power supply here.

  6. djcc, its very very rare but it can happen.

    I heard only one story exactly like yours, you are the second one.
    Can't say those are bad medias but their reflectivity just not as good as expected.

    I would try the DVD-R booktype on those discs, see if the problem persist

    My drive is a Benq 1620 - the only utility I have for setting book type is their own utility, and it does not allow setting a DVD+R to DVD-R...

    Have thought about switching over to DVD-R discs to see if that helps, but as I originally mentioned, it would take a huge quantity of burns, which are then viewed in their entirety, to know if it made a difference or not. Not even sure that would be conclusive as the exact same disc might play without problems, or have a momentary pause or 2 during playback.


    SO, does anyone know for sure if stand alone players do something differently when reading DVD+/- R vs. DVD-ROM? If not, obviously, changing book type to DVD-ROM should make no difference at all.

    Reason I thought it might handle it differently is, why else would a player not be compatible with all media formats unless it read them differently in some way??

  9. I'm sure DVD Info Pro would allow to set it to "DVD-R".

    If you are really into it, ask "spath" (Michael Spath), I believe he writes firmwares for players.

    Does your drive allow for booktype change? Not all do.

    Well, you're right but I would think people should search the site before messing up threads.

  15. I've realized that if a DVD-/+R plays on a Sony set top player, it'll play on anything.. very picky players, as lordsmurf and a few others said.

  17. I suspect write speed as well. I just burned a MAXELL 002 at 8x, (and DVD-ROM bitset, BTW), and got a ton of errors in the last 20% of the disc. The media is rated at 8x.

    So I put a blank one into the BenQ utility QScan, and guess what? It recommends NOT burning at 8x, but at 4x max. Did another at 4x, no errors.

    Funny thing, both play fine on my two players. No doubt your player has something to do with it too.

    Good luck sorting it out.
    Pull! Bang! Darn!

    I just switched to DVD+R from DVD-R, but have been using DVD+RW as my preferred re-writables. I have a BENQ 1620 (dual layer, dual format) and the DVD+RW that I bitset to DVD-ROM are not even recongnized by my APEX 3120 and my Norcent DP-300. Leaving it (or returning to) DVD+RW works fine. Iàm thinking bitseting is not all it's hyped up to be.

    Thanks again everyone for your input - hope this thread helped someone else as well.

    For now, I'm going to chalk it up to Sony's reputation of being fussy with burned media. However, since my player does support +R, for the time being I am going to stop bitsetting to ROM and see if I notice any change.

    @ fritzi93 - I have not found ANY value whatsoever in the Benq Qscan utility - it will often report that my discs cannot burn at ANY recommended speed even though the FW suggests it will burn upto 16X on TY02 media.

  21. Oh well, I think it has some value. No DVD utility that I'm aware of is perfectly reliable. I'll scan with DVDinfoPro AND CDSpeed, for example, not trusting either completely. Nor do I think bitsetting is all the admen say it is. But it does allow me to burn DVD+Rs that play on my Apex.
