Not quite sure what you mean... if you open a video-page, for example, it has that large green arrow icon to scroll to the next video. The page reloads and is shown from the top. It works pretty much the same way on every other site, like facebook, flickr, etc. They just have very compact navigation and media pages fit into the screen when shown from top. They also have minimal "extras" on those pages, so reloads are near-instant. You may achieve same results by using templates with more see more compact navigation menus and by removing extra blocks from media page using builders.

Or, maybe, I didn't get you right, so let me know how exactly you see what you want to see :) ?
