Forum:YouTube Embedded Videos Acting Strange

Hello there! On every page of this wiki that has a video (that's nearly every page under category of "Roller Coasters"). The thumbnail shown before it is clicked on, is very squished. It seems to be a problem with Wikia videos only, because other YouTube videos embedded like this are not squished like this. Any help would be appreciated!

Here is an example page: Olympia Looping. MontagnaMagica|Talk 00:24, June 23, 2011 (UTC)
