My DVX200 will not record more than the minimum (30 Mbps) data rate for the cards I am using which are SanDisk Extreme PRO 128GB UHS-I Class 10 U3 cards. I have updated the camera to the latest firmware. I have also performed a full reset on the camera. I called Panasonic technical support and they did not have an answer for me. The camera functions perfectly in every other respect. But it won't record at the full data rate for any recording format. For example, I recorded for 57 minutes in the FHD 1080 All-I 200M format but the camera only recorded 25GB of video on my SD card. The readout on the LCD screen showed the space remaining on the card only dropped from 1 Hr. 25 Min. to 1 Hr. 8 Min after recording for 57 minutes. Please help!
