Crikey. I've just learned that although you can use regular mini-DV tapes in an HDV camcorder, maybe you shouldn't. According to wikipedia (today, at least): "Because HDV uses the same tape form factor as DV, users should be able to use any high quality MiniDV tape in their HDV camcorder. However, because HDV has a lower tolerance for drop-outs because of its long-GOP compression, many HDV users purchase either 'master' quality Mini-DV tapes or specially formulated HDV tapes."
But tapes advertised as being for HDV cost four times as much as regular mini-DV tapes. Surely this is a rip-off, comparable to the hugely-inflated prices of Monster cables? Please someone tell me that regular tapes from a reputable manufacturer are good enough!
