i spotted this way way before but thought it best to keep it to myself and let you figure it out all on your own 🙂
I noticed it this morning, but didn't think the video was supposed to play from the main page. Apparently it was!
Also, it's only the initial preview image of the video that is stretched out.
The problem is that you can embed multiple video types, and not just YouTube.

The videos I've initially linked are all the old ones I filmed on a film cam corder, and had to convert to digital, so they aren't very good quality in the first place.
A 720p video fills out the area a lot more

1080 would probably fill the whole area.
I'm going to ask the question anyway.
