i bought the WD live book yesterday and already having a heap of issues , connection was easy but streaming is the issue , i can play MKV via a usb but streaming from the live book the dnla enabled blu ray player wont read the video files mkv and mp4 and others, also my sons x box 360 is failing to read them , ive gone and linked it to the blu ray as a NAS and the video files now play but shouldnt all this be able to be done via DNLA , if anyone has tips or advice it would be most welcome.
