Sub playlist configuration for padding playlists

Hi,

Here is my scenario.

playlist1 - 3 videos
playlist2 - 5 videos
playlist3 - 4 videos
playlist5 - 6 videos

I want to play all of the videos at least once. So I need to cycle through the playlists a total of 6 times. After the last video in a list is played I will start back at the begining.

Here is the kicker. Between each video on playlist1 playlist2 and playlist3 I want to play a video from playlist5.

I could create a rotation like this:

playlist1
playlist4
playlist2
playlist4
playlist3
playlist4

However some times when I save it says I can not use a playlist twice

So I could create copies of playlist4 and do this
playlist1
playlist4
playlist2
playlist4copy1
playlist3
playlist4copy2

But that does not seem to work either. For some reason one video on my playlists seems to be repeating over and over.

I am set to “round robin” “repeat”.

Is my configuration correct?
