Problems using Tweener

I’m using tweener in order to play through an embedded video inside a movieclip. The movie is relatively small sized (about 100kb) and whilst tweener works perfectly at playing it normally, when i try to play the clip backwards to its original position, the motion is quite jerky and some frames are missed out.

the code i’m using is:

[FONT=Courier New]back_btn.onRelease = function() {
Tweener.addTween(work_mc,{_frame:1, time:1.6, transition:“linear”});
};

I’m using the latest stable release for AS2

[FONT=Verdana]I was just wondering whether anyone else has had similar problems and if they could suggest any remedies to fixing the situation? I’m just looking for an easy way to quickly return back to reverse the video, but retain the same quality of motion as the original playback.
