Occasionally, you will encounter video clips that only appear to display the first frame when played in VLC. When this occurs the progress bar continues to move but no additional video frames appear to be displayed. “Scrubbing” across the video will sometimes allow you to move to a certain position beyond the first frame, but even this doesn’t always work. We recently had a DVR Examiner user ask us about this. They were reviewing AVI files exported from DVR Examiner and some of them played fine in VLC and some simply froze at the first frame.
