Tried all firmwares but no success.
LiteOns bit set utility (latest version) does not work on my machine.
It states unsupported drive detected ,it didn't work on my previous drive LDW851 either.
Older version of LO's bit set ver 1.04 does work tho and states,UNABLE TO QUERY BOOK TYPE SETTING MAYBE F/W NOT SUPPORT ,although this did work on the LDW851.
DVD info pro states IT SEEMS YOUR DRIVE DOES NOT SUPPORT BITSETTING.
I know this sounds stoopid and I'm getting confused coz others seem to be able to change book type ,am I doing something wrong ,or is this drive faulty ,or does the software not support it ?.
P.S. DVD Decrypter ( as Black Wizard stated) does appear to do something ,although book type stays the same before and after burning discs.
