That green line shows the frames that have been stored in the RAM Preview Cache. If you want the preview to start at the in-point of the layer, select the layer, press "i" (for in-point), then press "n" to set the work area to the current position of the CTI (Current Time Indicator). 

It would be very beneficial to you if you opened the Learn workspace and got familiar with the UI.
