DHett 0 Report post Posted August 2, 2021 MyGica A681B ATSC HDTV USB Stick - Necessary to use HiDTV software? I recently bought a MyGica A681B ATSC HDTV USB stick. I use TSReader and another application to read and document program streams. Neither application is able to recognize the tuner unless I launch HiDTV first. Is there something about the HiDTV application that makes the tuner visible to other applications? It is quite unwieldy to have to launch HiDTV each time I use the tuner.
