for speedo cable and front master brake cylinder access you remove a different cover. The video shows the 'front' cover removal, which will give you access to the back side of the ignition module (which also controls your glovebox and seat release cables) and the top of your forks.
Front cover is 6 screws facing the rider, 2 facing the front on either side of the tire and 1 bolt right in the middle, under the grille, hiding under a little tab that you pop off from reaching behind it.
Not sure what he's talking about with a screwdriver...I've never used one (nor would I) as a prying tool to remove the front cover.
Speedo cable and master are accessed by separating the headlight and speedo cover. I'll attach a few pics. That takes 4 screws facing the rider and then the 2 'Frankenstein' bolts on either side, down lower on the headlight/speedo cover.
You'll want to unbolt both front turn signals, first (I cover mine with a sock, then let them hang down, otherwise you're likely to scratch your paint). Take out the 4 visible screws and finally the 2 bolts on either side. Separating the cover is a PAIN...I also have used painter's tape to cover the flat area above the glovebox and under the rotating headlight/speedo cover to prevent scratching during this procedure.
With the side bolts out you have to pull out hard on the front and back covers to clear the female part where the bolt is threaded into. A putty knife or other prying device, wrapped in tape to prevent scratching, works well. I actually use a 'zip' tool, used for separating pieces of vinyl siding to get in there and pry. I'll show a few pics. This is very hard to explain...you'll probably just have to start working on it and come back here if you get stuck.
