I seem to get better results with 2.0.4 series than 2.2 series. What could be the problem?

For this version, I have a query. I wonder why is it that when I set the uTorrent options to be using only a single port for both outgoing and incoming connections (so that I can use QOS settings to set priority on it), I can't seem to get it work for my Windows XP x64 system. It does work on my existing Windows XP x32 system. I have checked settings on both uTorrent's configuration windows and they are already the same. Can anyone help me out on this? Thanks in advance.
