Probleme mit selbstgebrannten evtl. nicht mehr so häufig wenn..

Habe da was interessantes gefunden bei Cdfreaks.
Da ich es selber noch nicht testen konnte (kein Viperchip aber ein Brenner der Booktype DVD-Rom setzt)wäre es doch sehr interessant ob vorher ohne bitsetting und nachher mit bitsetting soich die kompalibität erhöht [img]smile.gif[/img]

</font><blockquote>Zitat:</font><hr />Changing the booktype field

This booktype field identifies the disc as either a DVD-ROM, DVD+R(W) or a DVD-R(W) disc and is for a big part responsible for the compatibility. Because this setting is overwritten during the DVD-R production process it can’t be modified afterwards, the laser of your DVD recorder simply can’t write to that part of the disc. During the production of DVD+R discs the space is untouched. Still CSS keys can’t be written to DVD+R discs because every DVD recorder and DVD player has a limit in its firmware to write or read to this space. However, there is no limit for writing the booktype field. Therefor a DVD+R(W) recorder will be able to modify this field by sending a command to the DVD recorder and fool the DVD player.

When the booktype field (bitsetting) is changed to DVD-ROM then DVD players are fooled and will think the user has put in a DVD-ROM disc instead of a DVD+R disc and will read it accordingly. This results in an increased chance that the player is able to read the disc and that’s why the ability to change the booktype field (bitsetting) is essential to a lot of users. Certainly owners of a DVD player that requires this field to be set to DVD-ROM, in order to work properly, will prefer a DVD recorder that supports setting the booktype field.

DVD-R bitsetting

Although you will understand that it’s not possible to change the booktype field for DVD-R discs there still excists a DVD-R bitsetting. Some claim that this increases the compatibility but this has not been independently confirmed by anyone and as it’s technically impossible to change the booktype field it will still be possible for the hardware to find out that a disc is a DVD-R. The booktype setting for DVD-R discs seems to be based on a workaround that has not been proven to be working.

According to Michael Spath who studies both the +R and -R format and is known as an expert on technical DVD recording issues; "the trick is based on the fact that some drives read the booktype from the last border-in and not from the lead-in. Therefore if you create a second session on the disc you will create after the first session a new border-in, where you should normally copy the informations from the lead-in (including
the book type). With this trick, you instead write a DVD-ROM booktype in this second session, which violates the - standard. Also drives which read the booktype from the lead-in will not be fooled by this method (eg. some Pioneer drives". An intresting discussion about this can be found here.

Tools

The booktype field can be modified by several applications. Best known is Nero which allows you to modify field the booktype field for several brands of DVD recorders. Companies such as Lite-On, BTC, NU-Tech, Ricoh and BenQ have released tools to modify the booktype field. Firmware hacks (E.g. NEC) also are able to set the default booktype to DVD-ROM. Other companies such as LG have announced it will add support and Philips automatically changes the booktype using the firmware of the drive. Plextor has till now said it will not support it because it's not according to the DVD+R specifications. On our forum you will find many discussions on the several applications.

It should be mentioned that burning a DVD+R-DL without changing the booktype significantly decreases the compatibility with existing DVD players and DVD-ROM drives.

Unfortunately it seems that many manufacturers don't care much about compatibility. If I have to choose between buying a drive that "matches DVD+R specification" and a drive that's able to produce discs that I can playback on all my drives, guess which product I'm going to buy.

Is there a up date on the 2510A?

I would like to comment on the statement on DVD+R format concerning booktype bitsetting.

In the official DVD+R format standard document it is stated that the DVD+R booktype is embedded into the ADIP (Adress in pre-groove) information. From that this booktype is copied into the lead-in. However, this may be changed in order to increase compatibility. The exact wording this is “Temporarily drives can set bits b7 to b0 to other values in order to increase the compatibility.”

As new DVD players will recognize the A1 bitsetting, we expect that this booktype issue will disappear gradually over time. Until that time alternative booktypes settings may be used to reach maximum compatibility.

Plextor has support for changing booktype with newest firmware for all PX708z 712 and 716

Pay attention to the way it can be done with 708A - Plextor introduced it in the last version of Plextools Professional + firmware 1.08

For the other models you can do it with other programs, like the last version of Nero+

I have found the hard way that Lite On burners with their book setting software does a better job at compatibility with dvd players. I have a Sony DVP S7000 and so far only Lite On burners with their bitsetting software has work for it.

Bottom line: if you have difficulty with your player with the -ROM booktype try a disc using a Lite On burner, I think you will like the results.

Now if Lite On will only improve the quality of their burners.

I want to know if you are burning data on the dvd-r or +r which booktype you need to select dvd-rom, dvd-r or dvd+r

das klappt NUR mit +r/+rw medien, und bringt beim cube nix.. der cube liest keine dvd-rom medien, jedenfalls nicht offiziell, darum bringt es auch nichts ihm vorzugaukeln es wäre ein dvd-rom medium.

haste es schon getestet ?
Wenn ich probs habe beim brennen, dann werde ich mal einen Rohli mit Bitsetting opfern.

P.S.
Man kann auch bei - Medien ein Bitsetting durchführen.
Falls du einen link benötigst das dein - Brenner es auch können sollte dann frag mich und ich gebe dir den Firmware Link

Samson Blinded: A Machiavellian Perspective in the Middle East Conflict also scored high in all categories it was nominated. Google earlier banned advertising of that blog for unacceptable content.

Samson Blinded's author advocates religious state of Judea at the border with Israel and expulsion of Arabs. Obadiah Shoher denies democracy dominated by liberals and Muslims and calls Israelis to oppose police efforts at removing the settlements. His other point is dismanlting economically unbearable Israeli army and relying on nuclear weapons. However, he decried Lebanese and Iraq invasions.

Public opinion seems to strongly shift the the right in Middle East issues. Any thoughts on that?
