I’m not sure, but it seems Plex is miscalculating MPEG-2 bandwidth.
Most of it should be between 8 and 10Mbps - not Gbps.
It’s hefty, but not that hefty.
Not all transmissions are MPEG-2 maybe.
Not sure about your Live TV, but mine is ALL MPEG-2, ALL Interlaced, and ALL a PITA for Plex to handle Live. I simply don’t do it. <—because it buffers, studders, etc.
Depending on your tuner you may be able to have it ‘transcode’ so it’ll deliver a 264 stream that will Direct Play, but I have no idea how that’s going to work for Live TV.
Live TV is tough for Plex - way too easy for your TV.
You can try to use Plex For Windows or Plex Media Player and stop them from de-interlacing to see if the TV will, like mine will, De-Interlace anything that comes in Interlaced on any port. That’s quite rare, but you could try it.
The point is you have to get Plex to Direct Play 1080i and the Audio. Plexweb absolutely will NOT Direct Play MPEG-2 or AC3.
If you can make that happen, you’ll find out pretty quickly if the TV will De-interlace. Your eyeballs will explode if it won’t…lol
