Keep in mind QoS will only apply to packets you send unless you have  
an arrangement with your ISP to prioritise traffic coming from their  
end.[1]  Another point to make is that not all routers on the Internet  
honour QoS flags.  The best way to ensure  a reliable gaming  
experience is to shed some load on the link you use, which may mean  
some old fashioned people-skills with  the other person you share the  
router with ;)

Best of luck,

James

[1] OK, you *can* apply QoS on packets from your router to the LAN,  
but what's the point??  You've already received the packet and your  
LAN will easily be several times faster than your Internet  
connection.  QoS is only really useful when links approach saturation  
and/or you're routing traffic from a fast link onto a slower link.   
QoS on a slow link to a fast link isn't particularly useful.
