Not using Raspberry/Banana/Orange Pi
But have been testing Odroid-C2 as a server with 6 HD tuners (Dual and Quad HDHomeRun). Testing with multiplexed stations and some times recording up to 15 OTA shows at a time
Have no need for transcoding as all Kodi frontends are wired GB connections
BTW: Also runs frontends(Libreelec) better then AMD Phenom II with Nvidia graphic adapter
