Bitsetting questions...

[Nilfennasion]

I am contemplating upgrading my GSA-4120B to a GSA-4163B. The main reason for this is because I like the option of having bitsetting. Anyway, to cut a long story short, I have some questions:

* Is it possible to bitset a disc after it has been burned and finalised?

* Does this allow any more options in terms of the content of DVD+R DL backups? I would like to be able to remove copyright messages since, having seen over 500 DVDs, I often see the damned things in every language of Europe and then some when I close my eyes.

* In short, is it really that big a deal, on top of faster burn speeds, to justify the upgrade?

All bitsetting does it make the disk look like a DVD-ROM, rather than a burned disk. Because it is still physically a burned disk, it still may not read any better in your player. It has absolutely not impact on the content of the disk (i.e. you will still get copyright notices etc., although if you copy with DVD Decrypter you can remove the PUOs and skip over them). It has to be done while burning, so you can't retro-fit bitsetting to the disks you have done so far.

Okay, that clears everything up for me.

I have just purchased a Pioneer 108D and updated the firmware with Piodata 1.18. The reason I did this is because my Yamaha player does not play DVD+R discs.

I burned my first plus disc tonight and it played fine in the Yamaha as it was a DVD ROM disc. DVD ROM discs are compatable with all DVD players regardless of age.

Commercial pressed discs have a format of DVD ROM, so I guess if you have the luxury of bitsetting available, it is indeed a bonus.

Oh cripes, not you again.

In case you did not see my reply to guns1inger, he has told me everything I need to know already (mainly that one cannot retrofit a booktype to an already-burned disc).

I guess you missed that part in the other thread where you were told that a factory-pressed DVD(-ROM/-Video) and a burned DVD with the identifying bits set to DVD-ROM are not the same thing. Even one of the moderators came in and told you that you are wrong and seem to be in over your head.

The reason I asked was because of the simple fact that I would like to see whether a bitset DVD+R DL increases the marginal compatibility of this format to play on my existing equipment. Not because I need to see you spreading information that is wrong. We get enough of that as it is.

I agree that bitsetting does make it more compatable with MOST players but not all. I have burnt a few +R discs with bitsetting on that where not readable in my apex dvd player(less than 2 yrs old), but playable on my Zeinth dvd player(5 years old) and my Toshiba player (less than 2 yrs old also)! Also I have burnt a few DL +R's with bitsetting on that the Zeinth and Apex wouldn't recongize but my Toshiba played perfectly. I believe, could be wrong, it all has to do with what dvd media you use and how the dvd player was made.

Nilfennasion,

I burnt "Eyes Wide Shut" international version with either dvddecriptor or dvdshrink, can't remember. I took the region coding out so that I could play it on my USA dvd player. It plays Perfectly on my Toshiba progressive scan player. Can't remember the model number, but it's the one with the discrete 5.1 analog outputs not just the one analog or SPDIF cable. My other players play if fine up to the point where it switches layers. The players start skipping and pauses then shuts off. I used verbatim DL media with bitsetting turned on. Burnt with Mad Dog Multimedia 16x DL burner, which is just a rebagged NEC 3500. Hope this helps.

That would be an incompatibility with the players. It seems the vast majority of players were made without the anticipation of being asked to play back recordables with two layers, which is where all the current fuss about bitsetting and compatibility comes from.

The player I am currently using will not play back DVD+R DL because it cannot align the laser to read the pits in either layer, which is what master blinky above seems to be having a big problem with. But don't tell him it's his problem, okay? He still likes to think it's that of everyone who knows better.
