Lost YouTube videos when importing from WordPress.com

I successfully imported my files from wordpress.com into my www.ads-software.com site. However, all the youtube videos I had inserted in the WordPress.com site (https://thedumbingofamerica.wordpress.com) aren’t showing on the new site (https://www.thedumbingofamerica.net).
I had used the ‘add video file from url’ feature on wordpress.com and am wondering if that’s the cause of the problem. I’d hate to have to go back and embed every video I’ve ever posted on my site (over 100). Is there a quick fix?

Thanks in advance!
