So, the ISP still doesn't figured out the way to throttle this version? Glad to know it, since my speed incredible slow all suddenly today. Yesterday it was okay with stable download rate. It might be to low seeders then. 'Cause I tested it with 4GB download, I got stable 40kb/s speed (it is my max speed), it got good seeders numbers than the leech. So, maybe I messed up some configuration, or this torrent just full of 'hit and run' peers.

Did you tried the new 2.1 alpha version? It fixed DHT limitation and peers connectivity. It also got auto port forward feature and other fixes. Might worth the try, clean every utorrent configuration files and other leftovers though (registry, etc), I got an issue where I can't install the new alpha version. But then, I remove all remaining leftovers from 2.1 beta version, and it works, some users still have that problem though.
