If you can burn a regular dvd and bitset it to a DVD-ROM format, can you also do the same with a Dual-Layer (DL) DVD?

I ask this because I do not have any dual-layer discs. I do have some regular DVDs that I can test to turn it into a DVD-ROM.

Do all burners have DVD-ROM Bitsetting function if it can burn DL discs?

this page describes bitsetting as a function to make DVD+R and DVD-R compatible.

Can bitsetting make DVD+R more compatible than DVD-R

Certain older DVD players, including DVD players in some laptop computers, will not load DVD-R or DVD+R disks at all because those formats did not even exist when the player's firmware was written. However, by changing the bitsetting on a DVD+R to DVD-ROM, those players should be able to load and play the DVD+R.

edit

it looks like bittsetting only changes the first four bits on a dvd (known as book type) to tell the dvd drive what type of disc format is in the drive

Setting the Booktype with ImgBurn | Articles - Digital Digest

Use the bitsetting (Set Booktype) feature in your bitsetting software to set your DVD+R/DVD+RW/DVD+R DL Media (Only DVD+R/+RW Media) backup to DVD-ROM for much higher compatibility with older DVD players and Game Consoles such as XBOX and PS2. Bitsetting is done during the burning process when bitsetting DVD+R Media. DVD-R Media Bitsetting, Booktyping is at the moment debatable [DVD-R Bitsetting Thread].

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. - Quote from CDFreaks.com

You can also set/change your DVD+RW Media's bitsetting/booktype, but the difference is that you can bitset DVD+RW Media even AFTER you have burned it.

Here are directions on how to Bitset or Change the BookType with DVD Decrypter on Plextor, NEC, BenQ, LG, LITE-ON, Nu Tech/QSI and Ricoh Burners. There is no one best bitsetting utility out there, if it works for your burner it works. You can also use Nero to Change the BookType or BitSet, check out our NERO Booktype Tutorial for directions how. Note: Only Nero SmartStart/Express version 6.3.1.6 or above support BitSet or Changing the BookType. If Nero and DVD Decrypter does not Change the BookType or BitSet your DVD+R to DVD-ROM please refer to other Bitsetting Programs

How to tell if the disc you burned is already booktyped to DVD-ROM? - Read the disc using programs such as DVDInfoPro, Nero CD-DVD Speed, DVD Identifier, or Imgburn to read your (already) burned DVD Media.

??????????????????

does my drive support bitsetting to dvd-rom or not?

[Mak213]

IT would depend on the software. As his 2nd quote says ImgBurn can do it. I would think that all drives could do it. But they may not since that is really old tech.

The only way to know for sure is to try it.

thanks again Mak

Again I don't have DVD+DL disc that I have access to. But let me rephrase my question, if I can burn a regular DVD+R and bitset it to DVD-ROM, will I be able to necassarily do the same to bitset a DVD+DL to DVD-ROM? Is burning each format have its own standalone system or how do optical drives work anyway?

hi try here CDFreaks.com - Worlds largest consumer electronics community

I do not think that you will be able to use a DL Disc and burn it as a DVD-ROM. Back then DL was not know and never heard of or thought of.

So it might be impossible for todays technology to set a DL Disk as DVD-ROM bitset and work.

Again this is all speculation cause it is not common and people dont really try to do that stuff anymore. Your best option will be to try it. Most people dont want to use bitset DVD-ROM cause it isnt used anymore. Except on older consoles.
