How to download full *private* playlist from youtube by IDM ?

[vegeta4461]

I bought IDM for this purpose- Try download a full private playlist from youtube ,  and for some reason when I enter the private playlist and copy the url it only download a html file and not all the videos... 

*If I enter every specific private video of the playlist, I can download with the IDM but it is a hassle! 

What can I do? Someon knows how to download a complete private playlist with IDM?

Unless IDM is somehow exploiting YouTube I'm not sure how it could download the playlist - unless it is your own private play list and you're having IDM download as you.
