What is the best way to achieve smooth scrolling?

Hi all,
I'm looking for the best way to achieve smooth sideways scrolling. I've used the 'Making the view follow the actor' methods in the GE tutorials but when I replace the graphics with my own (just grey rectangle blocks) then every so often the image shakes and isn't smooth.
Does anyone know a better way to achieve smooth scrolling?
Many thanks,
Laddsa
