I am having trouble embedding a video into a web page, using the latest version of Designer Pro. I create a placeholder object and paste the embed code from YouTube into the Web Properties. When I preview the page, the video is hanging off to one side with the right half of it cut off. When I press play I get a generic error from YouTube and the video does not play. I have tried several different videos and I also tried matching the placeholder size to the size specified in the embed code but nothing helps. Same problem in IE and the latest Edge Beta.

Does anyone have any idea what the problem might be? I haven't overhauled our site in about 5 years and everything works on the old site.
