The HDMI IN record function (Z9x) is erratic, it never completes the stipulated time recording and stops midway intermittently. This seems to be an inherent problem right from it's first FW and has been overlooked so far. A request to the FW developers if they could please resolve this anomaly at the earliest. Thanks.
