Actually you should save your background as animbrush (if possible using a resolution bigger than the final one), move the handle point to top left and then use the move tool to make it scroll through the desider frame range and for the desired amount of pixel needed; i used to do this kind of animations but its been a while since i used dpaint last time...
the keyboard shortcut seems to remember on dpaint 4 was shift+m
