I have several RelLink 410 series with the SD cards. When I download the files from the camera it saves a *.h264 file which I can’t play or convert to anything else. Any idea what I can do? If I record files to my local PC it saves a *.264 file. I can play and convert this with VLC media player but not the recorded *.h264 files on the 410 SD. If I rename the *.h264 to *.264 it won’t work either.
