Inserting videos in Tagdiv's Newspaper8 Theme

Hey guys! I’ve purchased the Tagdiv Newspaper8 Theme almost a year ago. Everytime i try to insert a video via Wordpress OR with the youtube plugin, a giant space is created below the video. Can anyone help me to solve this permanently? I don´t know wherelse to find some help :confused:

Maybe you should reach the author of the theme and report the problem:
