Activated torrent and JDownloader simultaneously. JD finished after 2d 6h while I had to nurse it sometimes. Torrent will need 3d I guess but delivers a more constant data rate while JD has a lot of peaks and waiting time.

What I noticed in torrent regarding the PAL-iso: I have two different torrents containing the iso-file: One did never finish (69%) and contains 3962 pieces while the newer and complete one contains 15849 pieces.

Piece sizes can be changed per torrent. The torrent I created has a small piece size (512KB) to allow for greater reliability of data with poor connections.

Personally, I find torrents to be more reliable and friendly than CrapidShare. While downloading my original copy, JDownloader/Crapidshare ended up discarding a total of about 800-1200MB of correct data due to intermittent connection drop-outs (I would have got similar results from a torrent with a 200MB piece size).
