chewitt my main server back end is an x86_64 based system with two quad PCIe cards using TVH and full Kodi as a front end on Ubuntu 22.04 LTS. It’s absolutely fine.
I was trying to get the MyGica USB DVBS working on the RockPro64 purely as I had it lying around and was interested to see how DVBS would operate on a SBC. It works on Windows fine, tunes all available channels on 28.2e and is very watchable.
The fact that there is actually three revisions of this unit obviously doesn’t help trying to locate the correct firmware for the model I have. It seems v 1.5 was working at one stage, v2.1 not sure and no reports of v3.0 working.
I’m continuing to investigate this elsewhere and hoping that I come up with a solution for LE at some stage.
