Auto Bloh post Youtube are not responsive!

Hey! I have a small problem. I use the auto blog post! Works fine for images and text. I have also received youtube work via auto post! But movies are not responsive via mobile! How can I solve this problem? The most of the traffic will be from mobile! Please look at the video post i link to!

Best Regards / Stefan
