Good video, but I disagree with the toe straps and with starting at the valve. You don't need toe straps to hold the tire. And it does make a difference where you start inserting the bead. You should always start opposite the valve, and finish at the valve; otherwise, how are you going to get the bead together into the well of the rim opposite the final section of bead insertion? The final section has to be valve, because there's no room for both the valve and the two beads at the valve hole. It's like the guy in the video has contradicted himself about getting the bead into the well!

Also, wire beads are actually quite easy to get on. Folding tires with kevlar beads can sometimes be very difficult, especially when they are new. Contis are pretty bad; Vredesteins are usually pretty good. The Kevlar does tend to stretch a little, so after the tires been on the rim at high pressure, it's usually easier to get on after the first puncture. The thing with kevlar is that it is possible to mount it improperly, so you want to inspect the bead, making sure it s seated the same way on both sides. Otherwise, you may be in for an unpleasant surprise when you inflate it to 120 lbs. You'll see a bulge, with the bead lifted off the rim and the inner tube visible. You've got about two seconds to deflate the tire before it explodes...

The absolute worst thing that can ever happen to you cycling is having to change a tube in a cold rain, with frozen hands. I really hate that...
