there is a sandvine workaround in this thread:

it seems to help some people

some additional things to do which help a lot (the first two are essential IMO):
-use a BT client with encryption, like uTorrent (best IMO) and force encryption, or Azureus (use R4 encryption)
-use a port for BT between about 45,000 - 60,000
-limit your download speed on torrents to the same rate that you can upload, so when you complete your download, you will have uploaded the same amount that you have downloaded. Then, when your ISP cuts off your uploading after completion, you still have a 1.00 ratio (or close to it) This is kind of a last resort method, as you will have to wait longer to listen to a show you really want to hear, etc.
