It happens both in HD or standard. Msn, teamspeak,and Mirc I have also shut Msn off to no avail. The thing is, it has always worked fine in the past, I used to run Itunes or Media player, skype and many other things, and be somewhere like monkeys chinning (Lots of rs activity) with no lag whatsoever. I also after this problem upgraded my ISP to a 10mbps connection from a 910kbps connection.
