[mythtv-users] Raspberry Pi 4 FrontEnd Remote Control Issues

OK, thanks – did a quick preliminary search seems to indicate either no 
grounding (earthing) necessary, else to ground if necessary. (For others 
reading this, NEVER to either mains nor the hot/neutral. With U.S. 
three-prong plugs there is a ground prong and I would verify with a 
tester before connecting to the Pi.) There is also the possibility of 
ground loops causing other problems.

At this point I’m also thinking the possibility of the SD card being the 
cause. The original SD card was a well-respected brand, the backup card 
isn’t a no-name but I have had problems with the brand and it seems 
notably slower than the original. (I will be updating the original and 
using that.)

OK, thanks! Does make sense.

True: this particular remote I can do ‘trick shots’ with to control the 
TV: bounce off the ceiling, over the shoulder, etc. Will see what 
happens with the RPi.
