OP's picture is an upscaled feed. There is no native 1080 Spice and Wolf.
hint: very few things come in 1080 because it wastes a lot of bandwidth. You can air 2 shows in 720p for the bandwidth cost of a 1080p feed, so why bother. There are very few shows that would even really benefit from 1080 anyways, and those you can get on HD-DVD or BD. everything else looks fine in 720p.
