The last couple days I've been having an issue with Channels crashing and restarting in the middle of playback of live TV as well as recordings on a Firestick 4K. The video and audio briefly freeze, the screen blanks and it goes straight to the startup "Preparing your TV" screen. A specific channel seems to be doing it mostly, but I noticed it once on a different channel today. Last night watching Colbert, it crashed about every two minutes of playback.
I'm watching away from home and using original quality/not transcoding. Both ends are on symmetrical gigabit fiber ISP's. The server is pointed to an HDHR on a clear-QAM cable system. The HDHR reports 100% on all three signal metrics. Could this be Channels reacting badly to MPEG2 glitches?
I noticed this started happening right after upgrading to 4.1.0, though it could be coincidental. I've submitted diagnostics.
Any ideas?
