Just upgraded to ppt 2013 from office 2007 professional. In my 2007 ppt the .avi or .mpeg files played seamlessly when I checked on loop continuously option. Now with ppt 2013 the video does loop from last frame to the first frame but there is a lag of 2 seconds (it appears) and therefore it is not seamless. Any option for me to show movies seamlessly in 2013. Thanks.
