I ran an Ubuntu machine a while back for chip verification. It worked fine. So later I tried to use one as a DVR. That worked, but then failed after the first update. Then later the special hardware drivers I needed got upgraded so it worked again. Then the OS got updated, and it failed again. Then the hardware makers gave up and stopped updating their drivers for a constantly shifting Linux environment.

Went back to Windows 7 and got it all working again. Had to upgrade for various reasons to Windows 10, and Microsoft had stripped out their DVR software for no particular reason. Said "screw it" and subscribed to Netflix and Amazon Prime, and started watching YouTube.
