I use BitComet and got it in a couple of hours, or something. Have you restricted your upload speed to something insignificant? That could lead to a decreased download speed. I rarely get a share ratio of 1.0+ with hot new torrents in the time it takes to download a single episode despite the fact my connection is symmetric (2/2) (I did get 1.3 with this episode of Mai Otome, though, when the dl was finished).

Seeders shouldn't be a problem. There should be a huge amount of those around for this particular torrent... Check that no spyware is hogging your bandwidth. Edit: And pause your pr0n downloads until the Mai Otome dl is finished...
