I've been using Plex Media Server to stream video from a computer on my home network to my TV for years. So, if you're going to run you own server or just stream video to your old TV via Wi-Fi, get the Nvidia Shield TV Pro! I don't know what happened to the Chromecast- it worked well when I first started using it, but performance degraded to where it was unusable. Best of all, the video is now perfect, and my Jellyfin server streams perfectly again. The NSTP replaced the Chromecast and the Bluetooth transmitter, and even with my Sony Bluetooth headphones that don't have the the low latency codec, audio and video are in perfect sync. I ordered an Nvidia Shield TV Pro (NSTP). I did a little research and decided to replace the Chromecast. Now I'm wondering if the problems I was having casting video from VLC on my computer to the Chromecast dongle (see the original post, below) were because the Chromecast was starting to crap out. I tried factory reset and it didn't help. So the problem seemed to be the Chromecast dongle. I'd stream the same video on my computer that is wired directly to the router and there were no issues. When I was seeing problems, Chromecast always reported excellent signal strength. My Jellyfin server couldn't stay connected and was often unwatchable. When I didn't have the circle of dots, I had very low quality video. The problems I was having with TV streaming were buffering issues with the dreaded spinning circle of dots showing up and interrupting almost everything I tried to watch, whether it was streaming YouTube or Netflix via Wi-Fi, or coming from my Jellyfin server. I also had some Bluetooth earbuds that used the aptx low latency codec so the audio and video stayed in sync (a problem with my Sony WH-H1000 headphones I got from Costco a few years ago).

I had a Chromecast with GoogleTV plugged into the TV, and a Bluetooth transmitter that used the aptx low latency codec connected to the TV via optical fiber. Over the last several months, I've been having increasingly frequent problems with my TV streaming.
