I watched a m4v video file made from a Blu-ray disk using the MPW, a Kindle tablet & app and an HDMI cable connected to the Kindle and on to TV while vacationing rhis summer. It worked great.
I used the MPW as the media server, the Kindle was running the Avia app and started the video playing, and HDMI cable got it on the hotel room TV. Kindle tablets (unlike my iPads) have a mini HDMI out jack and is one of the reasons I even bought a Kindle a few years ago.
