Only DVD+R, DVD+RW and DVD+R DL media can be booktyped. The actual booktyping takes place before the DVD is burned ...

The program in 9mmRuger's link is DVD Decrypter and unfortunately it has been removed from this site ...

It is still available out there in cyberspace ... you just need to look for it ...

one word: "COMPATIBILITY" w/ standalone players if booktyped...

when you booktype dvd+r/dvd+r DL to dvd-rom, it gives you the BEST chance in terms of compatibility on ALL your standalone dvd players~ :)
meaning, your chances of your burned disc being able to PLAY on some more "finicky" dvd players are greatly increased~

in terms of compatibility, the order of formats goes like this:

1. dvd-rom
2. dvd-r
3. dvd+r
4. both dvd-r/dvd+r DLs

so, it's beneficial to ANYONE who chooses to use dvd+r/dvd+r DL format to booktype (another term for it is "bitsetting") their media to dvd-rom~ :)

good luck~

?What is Booktype /BitSetting?

 Physically there is a difference between a DVD-R disc and a DVD+R disc that is made during the production process. During the production of a DVD-R disc the lead-in is pre-embossed (pre-written). This overwrites parts of the DVD that contains information about the disc. E.g. the CSS key (part of the copy protection) is in this part on commercial movie discs (This is why you can?t make a 1:1 copy of a DVD). But in this space there is also room reserved for the so called ?booktype? field.

?Changing the booktype field

 The booktype field identifies the disc as either a DVD-ROM, DVD+R/RW or a DVD-R/RW disc and is, in a large part responsible for compatibility. Because this setting is overwritten during the DVD-R production process, it can?t be modified afterwards. The laser of a DVD recorder simply can?t write to that part of the DVD-R 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. Therefore, a DVD+R/RW 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 is changed to DVD-ROM, 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 will be able to read the disc and that?s why changing the booktype field (or bitsetting) is essential. 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.
