No, it's dvd-r dl. For some reason, experts call +R dl a "double layer" and the -R DL is called a "Dual Layer". My DVD player only supports the minus system and I want to burn a DL disc so I need -R DL.
I also discovered this media is so new that none of the superstores (BestBuy, Circuit City) carry it but there are several on-line vendors that do. So far, it looks like Verbatim and Ritek are the only ones available.
