I have a brand new SOHW-1633S dvdrw and have downloaded liteons bitsetting tool. I thought from reading the text for the tool that once it is set to dvd-rom it would stay that way unless set back to normal. Well it keeps going back to normal every time. I also had a LDW-451S that I had set booktype permanently to dvd-rom with omnipatcher but am afraid to use omnipatcher with this drive because I started having problems with my 451. I want all my burns to be dvd-rom but don't want to have to set it every time. Am I doing something wrong with the liteon bitsetting tool? Thank you.
