I've just finished testing the FireTV Stick, using Perfect Player and the NFPS m3u Playlist for accessing the IPTV service.
Quite Impressed.

A few pointers ...
- You need to install ES File Explorer and Perfect Player from the appstore.
- You need to go to settings /device /developer options /unknown sources -ON /ADB debugging -ON
Use ES File explorer to import through your network to a file sharing enabled PC, your m3u playlist. (or you can enter the external URL)

Below is a link for Perfect Player on Android STB's (a little different than the fireTV in operation, but the same to set up.)

For users that use Kodi, here is a modified keyboard.xml file to add functions to your FireTV Remote.
