How do I get video to play back at same speed on all PCs?

I’ve got a flash CS3 slide presentation with a series of FLVs streaming locally & syncing with text & graphic tweens on each slide.
The problem is the presentation is going to be used on a number of different PC laptops & on testing it runs at different speeds form one laptop to the next.

The FLVs are all saved on the laptop along with the SWF so there aren’t any bandwidth or connection speed issues. But is there any way of ensuring the speed of the video & the text tweens on the slides remains constant & therefore in sync no matter which laptop it’s played on?

Any help much appreciated.
Cheers.

I don’t think that you are ever going to get this working at the same speed. Rather than playing the flv and having the tweens happening over the top it would probably be a better idea to put cue points on the flv. Then as the flv plays and gets to specific points it can trigger the tween. This means that even if there is a difference in playback speed it will trigger the tweens at the correct time.

I don’t have an example to hand, but the live docs are handy in this case (note - check the comments at the bottom)
