I also believe they are port blocking...I try to Play Unreal Tournament online with RR and during peak hours my pings are 500+.Road runner says there is no problem if I can connect to the internet
Does RoadRunner take pains advertise "online gaming" in their commercials and marketing? I know Comcast does where I live. You might be able to threaten legal action for false advertising, if the product does not live up to RR's claims.
