multiple TVs and Live TV

I’ve got 6 TVs in my house. ow many DVR/Live TV tuners will I need?

You will need 6 tuners for them all to watch TV simultaneously. Less if not all TVs are used at once

so to make sure I understand, I need to have a tuner connect to the TV and to the internet. I’m currently spending a fortune on DIRECTV, but I could use the exiting cabling for internet connectivity?

You need 6 TUNERS. My HDHomeRun Extend has two tuners in it.
The tuner sits on the network connected to something to receive the TV signal. I use an OTA antenna.
You also need a device to stream the live TV stream to your TV.
Currently only iOS devices (iPad/iPhone) and Android TV devices (not Android mobile) can stream live TV from Plex.

how do you watch a particular channel? Select channel using plex app or tuner control?

through the plex app, currently on on IOS or ANDROID TV so you would need a shield or Mibox, razor etc. Other apps and devices are said to be getting live tv soon but no commitments on exactly which or when yet - Also add if you were watching the same channel on all 6 TV’s it would only be one tuner in use but if you wanted 6 different channels on all 6 tvs at the same time you would need 6 tuners or 3 HDhomerun Connect or extend. the connect model is selling refurbed for $49 the extend is $99. the only difference is the Extend can transcode. I have the extend but have never needed the transcode feature, When I add a tuner it will be the connect.

general idea here… either way, still cheaper than regular cable bills

or if you have smart tv’s then you would access DVR recordings via your library setup with your recordings in them.

Thanks you all for the great input. The diagram is awesome. So what I’m seeing is the TV signal still has to come from cable/DIRECTV or OTA. Plex does not provide a live video feed.

No, Plex does not provide the TV feed

Ok thanks. That means I’m stuck with a big DIRECTV bill. Our OTA is awful. All local channels are in a town 77 miles away.

Thanks again guys

Correct, Plex is the middle man in this and is accepting an input signal from the tuners and distributing it to clients that want to watch. Same thing it does for movies/music, but with OTA/cable TV.
