HP DVD Writer HP 1270d

I think this is a lite-on clone and I would like to upgrade the firmware. I can’t change the bookmarks as it is. If I upgrade the firmware will I be able to do that. I am having a problem with DVD+R not playing on my Home DVD player (Sony). Where do I get the firmware and how do you install it? There is no info available on HP’s web site for this Writer. Thanks in advance.
