I picked up a Raspberry Pi 3 and added a Flirc I had lying round, loaded it up with LibreElec and the Kodi add-on and so far things are working well with playing Blu-Ray full bitrate videos. I ordered a set of heatsinks for it just to keep it a bit cooler and I am still playing with some of the remote control keys with my Logitech Harmony remote. But so far I am pleased with the results for less than $100.
