Have experienced a problem when recording video comments. When recording the comment and speaking the sound does not match up.
When there is sound followed by no sound followed by sound in the video (i.e.you are speaking into the camera, stop speaking for a few seconds and start speaking again) the encoder removes all the dead sound space and replays all the sound back to back. This creates the situation where the video and sound are not in sync and all sound is played back-to-back, and the end of the video has no sound but you can see your lips moving.
