MSN ADcenter PPC

Hey Guys,
I have been running two similar campaigns one on Adsense and on Adcenter, I have found that the impressions and even clicks are significantly hire on the Adsense. The adcenter one seems like it is struggling to even get an impression. And according to the adcenter projection I am bidding high enough to average a 2.67 Ad placement with all my keywords (50+). anyone else seeing this type of difference between the two? And I do have the same settings in terms of geo targeting.
