I have Windows 8.1 and streaming works for me. Eg: on the PC click right on a videoand select “Play to” in the menu, it proposes “wdtv”, then video is seen on the TV screen. An alternative is using the Metro UI with IE or Windows media player and selecting the wdtv in the “devices” menu read entry of the CHARM toolbar.
Note that there was some problems with windows shares and network credentials in last 2.01.86 firmware, but the previous 1.16.13 firmware works OK for me.
