It will work with Dish. I'm not familiar with the Dish receivers, but you need the 5 colored connectors for best quality (Red, Blue, Green video and Red, White for audio). Setting this up on DirecTV for my tech savvy Grandma, we needed a $7 adapter from DirecTV.
It does work with Android devices, both phones and tablets. I have used both. The apps are currently $15 (one time purchase) there are no recurring or monthly fees.
It does require a hard wired connection to your router, but the devices you watch on (phone, tablet, laptop, etc) can all be wireless.
