Trouble Embedding video from a host site

My Site is TysonsTreasureChest.org and I am having an issue with the Videos Gallery page. Our local news station did several stories we want to share on our site and I copied the embed link from their site and use the text editor to paste the code.

There are a total of 7 videos, 4 videos from the same host site that we want to share on this page. When I paste the link and save the page, the two videos from other sites share just fine but only the last of the 4 videos from the news channel site will share.

I am new to WordPress, this is my first attempt at building a site so please bear with me. I am a quick learner but I have zero experience with embedded video’s.

Any Veterans out there that have some ideas I could try, I welcome you knowledge.

Thanks,
Austin
