move down to the section "Videos Showing Now"
Hit The "Lets Go Watch Some TV" link
On the tutorials page scroll down to your video which you will know is yours
you can select "Full Screen" from the YouTube Controls to get the bigger picture

The full screen might not show in HD for the first time looking (apparently it takes a day or so for YouTube to show HD videos automatically) so you can manually select HD by clicking on the cog looking thingy also on YouTube Controls, select quality & choose the highest one,, Boom there it should now be clearer.
Hope you are able to follow everything (not just getting the images in, there are a couple of more things that need sorting
I am making some more for you to also watch if you want regarding the layout on some of the other pages. I will let you know when they are available to watch too if you want to
