YouTube videos and Web Objects not working properly

I am having some trouble with embedding videos from YouTube while using web objects. I understand that insert video from a website and youtube doesn't work properly, so I decided to use the web object route. I added the video link, added the s to the http and it works. My issue is when I load the file into my LMS (cornerstone). I know YouTube videos work within the LMS because I have uploaded them previously outside of SL. Typically, what happens when a course is launched, a pop up browser is launched showing the actual course itself. When the screen for the YouTube video pops, it displays in a different browser as a full screen. I've tried the custom settings for the screen to reduce the size, but this doesn't seem to work. Is there a way to change the actual screen size when the video opens in another browser or are those settings specific to YouTube? My worry is that the learner will go to the page, the video will pop full screen in a new browser but then lose the actual web course behind it. I'd prefer it not to pop in another browser but actually open in the SL course, but I've read that feature isn't working properly when the course is loaded into an LMS. I've attached a sample. I am using SL2. Any help is much appreciated! Thanks!
