hi Loser 999,
Welcome to the site...
Im sorry to have to tell you this but all this configurations that your going to the trouble of I suspect wont help this issue. Your Using Shaw Cable and they are throttling WinMX. The reason your not seeing this with Limewire is they are not doing this to all p2p's just select ones, seems they know as well MX is best one..
I wish I had some great advice like changing ports or something to get around this but most companies that are doing this, Shaw included, are using software that picks up on and works based on WinMX Packets sent. They usually lie to the customers if you call and ask unless your very presistant..
At this time the only way to fix this and use WinMX is to change ISPs, which for many is not possible. They tend to like to do this in areas where there is no choice for service and can get away with it. Here is a thread that has similar content, Rogers and Shaw I believe are owned together...
