We don't know why Youtube refuses to play some videos on some devices, but we do know how to get around it on the Wii U. The secret is the browser's "Set User Agent" setting (tap your Mii, tap Start Page, tap Settings, scroll down the tap Set User Agent), which allows the browser to masquerade as another browser.
