I'm working on a website for a filmmaker. He posts his videos on YT and then wants to embed them on the site. Now, all of the videos are working except this one:

{youtube}AZfm_hC4xBQ{youtube}

It only shows the tags like that ^^^ in the article.
I figured it's about the underscore in the video ID. Now, since the video ID's are randomly generated I can't really expect the filmmaker to just upload it again until it has a video ID without an underscore... Is there any way to fix it so the tags include the underscore as part of the video ID?
