A good idea , but unfortunately the retail boxes are
wrapped in plastic foil and sealed with plastic ribbons

I just checked the specifications of the two drives
and came to the conclusion that most likely the
Polaroid drive is a rebadged BTC BDV-316C

I remember that on the retail box is written
"DVD Family: DVD-Video, DVD-ROM"

And that means no DVD+R support

Thanx again for your valuable help
