I’ve noticed a new tech issue when watching live sports OTA on channels that broadcast in 1080i (e,g, NBC, CBS, & CW). These streams create a video “tearing” artifact that I confirmed was not transmission interference. It does not occur on 720P broadcast channels (i,e, ABC & Fox).
This only happens with the 4th gen Tablo with MPEG2. Legacy tablo is unaffected because of h.264 transcoding.
I can only reproduce this issue on a Fire TV Select 4K. This may be a firestick Mediatek video driver (Firmware) issue if the MPEG2 stream is 100% passthru.
