This is the third generation of this product I'm buying. The first free wifi, was sober but impeccable. The second with wifi, perfect. It has network functions "extended" (more FB, Youtube and company) which, in my opinion, and seem completely superfluous saddled me on a media player (frankly, what's the point of FB on such device? It is better to use a computer / tablet / smartphone ...). Suddenly, you find yourself easily with slowdowns, crashes, etc. ever seen on previous versions. By dint of wanting to add more running after the fashion of social networks, WD has handicapped its product. However, the playback quality is the same if you avoid these trendy gadgets. He collects well over a movie to MKV HD 20GB, without slowdowns or stutters (but not passing through the library function that had planted me). For my usage (playing media files stored on hard drives), I preferred the older model, so a star less.
