Embed video on home page

On our site, www.brewreviewcrew.com, we used to just add the YouTube link to a post and if we didn't set a featured image, the video would show up on the homepage instead of an image. Somehow, that dissapeared. Is there any way we can get that feature back? Basically we just want the video to show up in line with our other posts. No featured image, no post preview of text, just the title of the post and the video that is embedded.
