It is required to make it work at home first:
- Connect MTV8000D to WiFi router using a network cable
- Make sure it's firmware 8.16 or later. If not, Settings -> System -> Firmware Upgrade
- Gadgets -> Video Streaming Setup -> On
- Connect your iOS device to the same WiFi router using WiFi
- Download and run the free Magic TV Streaming app
Making it work outside requires additional settings in router and/or app. Here's a (slightly outdated) reference: http://www.avbuzz.com/audio-video/201107/mtvu/0.htm
(Please ignore the section about connecting a video cable to itself.)
