I first thought it was a remote issue. After digging, it seems that my RC6 MCE remote (RHRC-11002) with a USB dongle should work “out of the box”. Indeed, when playing movies and when using the HDHomeRun addon, i can pause fastforward and rewind. But in Live TV, the button presses are registered by the dongle (red led flashes), but there is no response (at least not that i can see). If i need to post log files or outputs from dmesg or from ir-keytable or whatever, just let me know. Also, there is no response from irw, so it seems this remote is being seen as a keyboard. But, if i select the rc6-mce-lircd.conf file (My OSMC > remotes), then i get multiple button presses. Not sure what’s going on there.
I’m beginning to see a pattern here… everything can be enabled/disabled here in the Kodi/OSMC world. In order for the pause/rewind/fastforward buttons to work in Live TV using TVheadend, the server must be configured to enable timeshift functionality. Man, i feel like a tool! Once again, I must than @ActionA for helping me out on this one.
