Ok I found the control under (more play list action) this control is very hard to find and should be in the main controls when you right click the mouse and get player controls.When a video is playing you should be able to scroll down to video settings and be able to set the video loop control and be able to be adjusted from their.
Their may be a little bug in the way it is now you have to be playing a video and have the play list open on the right side to see the control at all however this control will not be their if the mouse pointer is not in the picture playing area meaning if the mouse pointer happens to be under the playing video in the video control area or the playlist area the top controls that say (thumbnail, add file, remove, more play list actions) doesn't show up at all the mouse pointer must be in the playing picture area for these settings to show up making these settings very hard to find.I will note this in suggestions
