If I have, lets say, a video that plays on the cover and also within another article, does DPS know that they are duplicate videos and it only loads once?
Funny you should ask. I was just looking at this issue myself. From what I can see, it does not know that they are duplicate. It loads them all as far as i can see. My vids are all in seperate folders in my structure. Maybe use a share folder for those vids?
