I DON'T know how NDD works through a BD player. I could only comment on the Blu Ray picture, not the audio or the networking capabilities of a player. But I've heard that most of the models now would store Youtube videos (a dream come true feature which enables one to compile for digital archiving favorite videos from the 1980s) and you could store your CDs (virtually eliminating your audio software clutter, of up to 10,000 CDs yata).
My recommendation is based on actual use - I own the LG BD-570, the Sony BD-S570, the Samsungs BD-C6900 and C6500, the Panasonic BD35, plus two more, including the Momitsu 799 which I fixed at Region B. I am ignorant of the models they sell on those mall or chain appliances stores, except Philips BRs whose picture is ho-hum mediocre. The models I owned, excepting the Samsung C6900, is not being availed locally, oftentimes the really good models won't see the light of day in the local stores. Hence, if you wanted the real deals (videophile-grade players) ask or await Anya and he'll bring you the cutting-edge stuff like he did for me.
I saw two LG BRs, apart from my 570 and I'm being objective here when I re-state that LG couldn't make a high-definition picture right. When I say sabog it means a dark scene of both 1080p and 1080i picture has qualifiable picture noise, maraming (infetisimal) na lamok bugging the picture. The color is not as richly nuanced or detailed as all the other brands (excepting my Sherwood BD which is the dullest, bar none). Di lang ako marunong mag-post ng comparative photos dito kaya di ko maipakita sa mga fellows ang observations ko. And when I saw those weak LGs, they're being coupled pa mandin with a Pioneer 508gx 50-inch plasma.....
