Hello, I just received the z9s today, I am currently running the latest beta firmware. I seem to be having issues playing some files from a Sony ax100 camcorder. The mediainfo for one of the files is below, the problem is that the files will play fine for 1/2 seconds, then the video freezes and the audio will turn to static/noise. Many thanks.
