This issue appears to be with the video player. Usually, when the video gets played once it repeats the play and starts from the beginning. So, the suggestion here would be to change the video player �??play�?? settings and turn off the �??repeat after playing once�?� option. This setting could be different for different players. For example, in Windows media Player it is called �??Turn repeat on/off�?�.
