I have a lightening fast gaming computer with a quality video card. When I play videos back, whether copied to my SSD or from the micro card in a USB drive, each minute of recording shows the video in front is not in sync with the rear video. At the start of the minute, they, as well as the audio are perfect. As it plays, they gradually go out of sync with the audio matching the rear camera and the front camera appearing to go into slow motion. After a minute is up and the next sequential file plays, everything is in sync and they gradually go out of sync again. Am I missing a setting? Is this a bug? Anyone else see this?
