One channel occasionally displays UHD VIDEO. SES demo channel. Do not know why. Just comes in, but cannot change channel and go back. WILL again say NO SERVICE! One possibility. This channel at times displays video which is still. No motion. So video comes in afterwards and plays fine. Hope that helps.
Also ACM/VCM audio channels not scanning in. Will scan in fine with TBS 6903 card. No Quality, only intensity. NO CHANNELS FOUND.
Firmware still buggy.
