AdMob and AdSense...a slight problem

Have any of you had success in having both of the these accounts? AdMob and AdSense that is. From what I know it is impossible right now to have both of these accounts. I originally signed up for AdMob successfully, however, a few months later when I want to monetize my YouTube videos, I couldn’t associate an account since I already had AdMob (Google was able to find my details to know I already had an AdMob account). If I can’t in fact have both of these accounts, would you guys recommend deleting my admob account and getting airpush so that then I can sign up for AdSense to monetize my YouTube videos?
