Seattle ATSC3 Status for January 30, 2021: I updated HDHR tuner and HDHR4K tuner firmware, Updated Firestick4k firmware, updated HDHR App Software, Updated to latest Channels DVR App Beta. Here is what I found in Seattle: HDHR App software runs all OTA including all new ATSC3 perfectly with stereo (not surround) sound when available. However on Channels App, there are audio/video sync issues when leaving default setting for video decoder to software, but sync is good when set to Hardware. So Channels DVR App is not decoding Seattle ATSC3 video correctly as it is jittery and behind the audio track until decoding mode is changed to Hardware. Channels DVR is also providing Stereo Audio (not surround) during the test period. Note that the normal broadcast channels had surround sound but it looks like the ATSC3 versions of those channels were only in stereo at the same time.
