Help with scroller game in flash

Ok, I’ve started making a game in flash and am just working on the rendering system now but I’m having a problem with render tearing when the background scrolls… I’ve tried 2 methods… first just use onEnterFrame() to call the rendering function which pretty much just calls attachMovie() with some coordinates that are updated when the user moves a direction and the second is almost the same but instead of looping attachMovie() I just update the positions of the background instances and call attachMovie() when I need to… more tiles come on to the screen

Is there any way to solve tearing issues with scrolling backgrounds? Or do I have to make the game screen by screen based? :huh:
