.wtv with Amazon Fire Stick and Kodi v17

I’m new to Android and Kodi. I did try searching as much as I could to find my answer before posting. I seemed to find only old discussion which may be a good thing.

I’m interested in buying a second gen Amazon Fire Stick as an inexpensive introduction to Android hardware or use with current v17 Kodi.

I’m specifically interested in support for playing native Microsoft Windows Media Center .wtv files which I believe are basically mpeg audio/video files in a proprietary wrapper but that’s about all I know.

Can I expect they will play in the aforementioned environment without transcoding?

I completely understand the Fire Stick is lowest common denominator hardware and plan to buy an Nvidia Shield for serious work but want something cheap for a downstairs 27″ TV that will primarily be used as a client for .wtv playback.

Thanks!
