Controling screens? help

Im using Flash 8 pro,

and im creating a presentation using the, flash presentation side (when you go to create a new flash) and it has already pre set next slide and previous slide slide actions with the left and right key buttons.

right my problem is in say slide 2 i have a video and then after that video theres some text and has a stop action on the text so the slide doesnt keep looping thats fine but when u press the right key and move onto the next frame thats fine but when u press left key to go back it doesnt play the video again instead it goes back to the stop frame

is there any way i can make it go back to the start of each frame when you go back to a slide ?

Thanks Martin
