Reverse movieclip

Hi,

Would like to ask if there is any script beside using tween to reverse a movieclip right from the start?

i face two problem, one is the reverse script. I tried to use prevFrame(); but the whole motion seem abit jerky. Is there any way to script it so that it will smoother!?

Another one is, is it possible to reverse the movieclip right from the start without going to frame 1? Cause i am loading this swf into another main swf, which mean i have another swf, the main one, to contain/load this swf.

hope i didnt confuse anyone.

thanks in advance. =)
