Video replay problem

I have the following problem. I use WMC to record shows. I then use MCEBuddy and Comskip donator to strip commercials using the WTV Unprocessed profile. When I try to play back the show I get a Decoder unsupported error in WMC. However I can play back the same stripped show using Kodi and ServerWMC on my computer. However when I try to access the same show from Kodi/ServerWMC on my Fire TV the show won’t play back. Nothing happens.

Why would Kodi work on my computer but not from my Fire TV.
