Hmmmmm. I can see the video fine. Using Firefox 12.0.
Anyway, this is dead easy, just get a sharp knife and think potatoes. As long as you have an eye, i.e. a sprouting bud, on a given piece that will be fine. Just cut through last year's stalk accordingly, keeping a bud and a piece of stalk on each bit.
If you haven't got any buds yet then plant the tubers on the top of a tray of moist compost for a week ot so.
