Again Thank you to you and your collegues for your time on this issue. Appreciate it was only ever meant to be a band aid but arguable its not even that 
That said it’s unjust to throw resources at a problem thats not really your fault.
I personally raised the issue with Amazon, a month later found myself full circle. I won’t hold my breath that Amazon will fix the issue. If they don’t, you guys were on the right track make the muscle (server) do the hard work! (its not far away from being a permanent fix ok band aid)
Please see it from the Plex customers perspective; I personally have speant £350.00 or USD on 4K fire sticks and £150.00 or usd on a Nvidia shield (cube) In total thats £500 or $ and I still can’t watch seamless live tv, yet I could do this if i purchased a £100 or USD on just a tv and plugged this into an aerial with a usb stick for a dvr (ok its not really comparable but hopefully you get my drift)
I would be much obliged if you could take a look at nvidia shield issues that on the face of it are identical to the fire stick 4k interlaced issues: It also shows that tuned channels become ‘sticky’ Nvidia shield tube (Android TV) Live tv issues, including other faults and crashes
