i had a script or an extension whose name was PREVIEWER or something like that i think.
I could just click on a video or a sound file in the project panel and the scipt panel would read in real time the video.
it had been a long time i had used it but now i can't find it any more since i reinstalled completly my computer 1 year ago.
Does it remain any body anything.
Or an other script doing the job :))
