I've had similar issues with BitTorrent. Of course, on a 2mb broadband connection, you're never going to get more than (approximately) 200Kb/s download speed - the real purpose of BitTorrent is to avoid the need for huge central servers, rather than to improve your download speed. An average seeder will also be on broadband and therefore can only upload to you at their maximum upload speed, probably around 20Kb/s. Therefore, you need to connect to at least 10 seeders, probably more, to max out your download bandwidth.
I just set things going and let it get on with it for a few hours... no rush
