I have an HP 940d ver.3H23 DVD burner with lightscribe. Is there a firmware update. Is it the same update as a 940i or a 940e? I've read that it might be a lite-on OEM and also that it is not. Don't know at this point. HP was absolutely no help. I know, I know... I can buy a new and better one but I would at least like to find out. To make matters worse I know nothing about "flashing" firmware. Yea I know I got lots of questions. Somebody want to help a confused old fart out??
