disable actionscript

I have main movieclip which needs to load movieclip B. How do I load movieclip B with all of it's actionscript disabled?

Problem is:.... I ma trying to preload a movieclip...but while it is loading ...it is playing ... and disrupting the rest of the main movie.... i tried putting it off stage but still the actionscript in it runs... and causes havoc.

I think you would have to know what actionscript is being loaded, and then basically write a routine that would overwrite the code with empty functions. Even that seems rather...laborious and I don't see any simple way to override AS.
