The rivet method, as shown, will not be all that strong since the end doesn't expand all that much; it wouldn't be difficult to pull it out through thin wood paneling. There is a similar type of pop rivet (technically, Pop is a brand name used generically; the correct generic term is blind rivet), called a split or exploding rivet, that, when set, expands with little wings sticking out that do a much better job of holding in soft materials, such as thin wood paneling. They are used exactly as the conventional blind rivets shown in the video. An example that shows the rivets before and after expanding can be seen in this link
Personally, I would prefer "Molly Bolts" (again a brand name used generically, the correct generic term being expanding hollow wall anchor) since they allow the object being anchor to be easily removed and replaced. The only downsides are that they require a larger hole in the wall than exploding rivets and the anchor are hard to remove (they are removable but it's a bear to get them out without further damage to the wall). Molly bolts can be set by either driving in the screw they come with or by using a tool similar to a rivet gun to pull against the screw.
