I used to use Flirc v1 on pc, back in the days of Windows Media Center, then Emby, then Plex, before i moved to a streaming box setup.
Worked very well. I could use any IR remote I wanted. Found for a few bucks at thrift store a DirectTV fully backlit remote with all the buttons things I could want. Was a bit of a pain to program the IR software, but once I figured that out, served me very well for PC based Media client usage. Kinda miss it.
Flirc makes a v2 dongle, one that is not fully transparent, no idea how good that model is.
