Just purchased this Netgear WNCE2001 for my WDTV live plus.. Was having streaming issues with my former Wireless "range extender", choppy playback, forever load times, particularly with MKV files. Tossed that thing in the garbage and hooked up this Netgear lil bugger and now streams perfectly.. Was only $59 as opposed to the other $90-$140 powerline adapters. Definitely recommend..
.. then again, im not sure how much faster, perhaps, the powerline adapters would be since I've never tried one.. Maybe it's worth the difference in price??
