I use Silicon Dusts HD home run and it works great. Live TV from home while I'm travelling is one of my primary use cases. I subscribe to a TV listing service. The DVR function is good too. My biggest issue was that I had to get a graphics card that could transcode on the fly then TV worked perfectly.

I have the same setup and TV works well but changing channel takes a few seconds. Not been able to work out why.

I have an Nvidia card which is more than capable of transcoding. How long does yours take to switch?

So not on Jellyfin, right?

With the Plex Pass, it was a one time fee (Lifetime Membership), and I've been enjoying it since (6+ years). I use CPU for transcoding.

Well, to be frank, even Plex's DVR could be better (e.g. I tell it to record a certain TV show, but I can't tell it not to record certain episodes, etc). I imagine other services do better on that count.

But my memory was that Jellyfin was terrible at it.
