Debian :: Rxvt-unicode And Vim Insert Mode

When entering insert mode in a text file i want to edit while using rxvt-unicode, there is a p being inserted and a whole new line is entered as well. when i hit the insert key, vim enters insert mode but also types a p and forces whatever line i am on down a line. if num lock is not on, it will not enter insert mode by pressing the insert key but if i type using the keyboard and not the number pad, it still enters text. vim/mode keys work normally in xterm. is there some unusual configuration required in order to get vim to behave properly within rxvt-unicode?
