I can turn them off when I'm watching it, but my dvd ripper seems to think they come as a pair. It doesn't matter too much, aside from having to rip things twice, once for the animations, and once for my ipod. Some of the English voices are ok, but the girls especially, they always seem to hire hyper cheery girls with annoying voices. Murakami sounds good either way, so he's ok, but I prefer the Japanese Archanfel.
