How to change LH-18A1P bitsetting/book-type?

Maybe it is a stupid question. I apologize if it is.

I have heard all Lite-on DVD-recorders can change book-type to DVD-ROM.

I got this image from Nero CD DVD Speed tool. It seems that my recorder cannot change bitsetting. I updated it from GLOC to the newest firmware GLOG and I tried to change book-type to DVD-ROM using BookType tool from Lite-on webpage without success.

Some help would be so much appreciated.

Welcome to CD Freaks.

The Liteon utility Booktype135.exe works fine but it doesn’t read back the settings properly so it’s rather confusing.

I think only DVD+RW can be bitset AFTER burning while DVD+R (DL) can’t.

Thank you for your replies.

I’m trying to bitset BEFORE burning an Imation DVD+R DL.

Regards.

Bit setting before burning is likely not possible. I don’t know for sure, but I think the media has to be written to in order to change book type which involves burning.

Right bevills1. Information about booktype is written when burning on discs lead-in (sector 60 something IIRC).
It’s only a matter of few bytes that tells the reader; hey I’m DVD-ROM… :slight_smile:

“Discs” booktype is stamped on disc in ADIP (ADress In Pre-grove).
