How about doing the MM method they use in their list box? Make a single clip for each visible element. Then, when you scroll, what you're doing is swapping out the content in the movieclips...
0 1 2 3 4 You have those 5 clips right, so when you scroll down, 0 becomes what 1 was, 1 becomes when 2 was, etc. 1 2 3 4 5 That way, Flash is only drawing 5 clips, and you're just swapping data out. This is how MM does it. No smooth scrolling, but it's hardly noticeable, esp considering the performance is great.
