I've recently overhauled my TV system in favour of Android boxes. Unfortunately on my Fire TV Stick 4K I'm noticing a problem with pixellation that seems to occur after 13 minutes (almost exactly). It's almost as if a buffer fills up and then pixellation kicks in until I either restart the channel or change to another one (then I'm good for another 13 minutes).
My nVidia Shield is ok with the Channels app.
I sent a diagnostics report about 90 minutes ago. I'm using a HDHR3-US tuner and my fire stick is connected by Ethernet through a USB adapter. Switching to WiFi didn't help.
Of particular interest is that if I use the HDHomerun app, I have no issues whatsoever.
The problem occurs on all channels.
The only reason that I purchased Channels is because it lets me select which HDHomerun tuner to use for which channel. I use two HDHomeruns because of a multipath problem I have with our local channel (CKCO, channel 13). I have to use bunny ears connected to that tuner to try to control the multipath problem. On that tuner, the channel has about 90% signal strength (I'm using a 10db attenuator) and is pretty much pinned at 100% signal quality and symbol quality. The diagnostics log is for that channel. Please note that I tried changing to Hardware Decoding from software decoding, but that didn't help.
I've spoken with SD support and they're convinced that it's the app and not the tuner since their app works fine.
Any insight would be greatly appreciated.
