Video streaming with WD 2go

In WD 2go description, it says that it can stream video with MP3, MP4, MOV and MKV format.  However I found that except for photos which can view online, other video format are not supported yet. 

Or any configuration missed?

You’ll only play what your device natively supports. On Android for example you’ll need to have RockPlayer or MoBoPlayer installed to allow playback of streams that your device doesn’t do on its own.
