I am using Imgburn and trying to set bookype with SH-S223F and I get success message but when I go back to this menu again and choose DL, the settings are unknown, that wasn't the case with my older drive ?
According to Opti Drive control, DVD-ROM writing is not (YES) or (NO) , but that's the same status in my older burner which used to booktype and show settings as DVD-ROM after restart also.
I tried burning.... and Imgburn said: booktype set as DVDROM so it works I guess, you need to set it up each time to make sure it doesn't reset with turn off.
One site said that it sets DVD-ROM for all media not each type alone, so I guess you need to set it up each you want to burn anything.
Good luck Samsungers
