"Torne?" "Nasne?" If you're wondering what the Hell these terms are, don't worry. Sony's PS3 compatible DVR systems currently have no announced release outside of Japan.
Just for an overview, torne (pronounced "TOR-neh") and nasne (pronounced "NAS-neh") are Sony's digital recording systems to record HD TV. torne is the name of the interface software, while nasne is the external digital tuner/recorder. Both are available in Japan in two sets: a torne + digital tuner set, and a torne + nasne bundle set. The major difference between the two being that while torne alone records directly to a PS3's hard drive, nasne has its own built in 500GB hard drive and can be used independently (although until recently, it still required a PS3 for its UI).
