I hired an electrician to rewire an outlet under my sink so that the switch above the sink can control only one of the two plugs. When he was done, I used the outlet tester and found that he hadn’t properly connected the ground wire. I wasn’t planning on connecting an appliance that needed grounding, but I think every outlet in the house should be grounded anyways as a matter of course. Got him to fix it before he left. That $9 I spent 7 years ago paid off as far as I’m concerned.
Nvidia Shield plugged into my TV running Jellyfin. Occasionally if I get playback issues I’ll open with an external player like Just Player, Vimu, VLC, etc.
Jellyfin used to be pretty rough with playback, especially if you watch with subtitles, but in recent months I’ve rarely had playback issues.
On PC I use mpc/madvr, but usually just to check a video file, not to watch a whole movie. I save that for the TV.
