Liteon/jlms dvd-163 dvd+r/dvd+rw

I know this has been asked a few times but i am still confused:confused: .
Does the 163 support dvd+r and dvd+rw?
At the store they told me yes a thousand times but in some posts people say no. Nero info tool reports only dvd-r/dvd-rw capable but according to compatibily list it does support the + format (al least with GH4W firmware. I have GH5S). The jlms website is a bit confusing: "Access all Format DVD, DVD-R, DVD-RW, DVD+RW, CD, CD-R, CD-RW Disc " What about DVD+R or does DVD+RW include DVD+R???

Have anyone tested this drive with the + format.
