I wouldn't use a Fire TV device for local media. Use Kodi on the Shield with a Gigabit network adapter. I've never used a Fire TV device, but I have my doubts it can bitstream TrueHD or DTS-MA, even using Kodi. If that's wrong, I'd appreciate knowing exactly what it can bitstream.I agree. Roku for everything streaming outside of netflix and a fire stick for kodi and local content. I have to use the Netflix app on my TVs to get proper outputs but that isn't a big deal.
