What silentweed was asking is for the code that is used to load your video or are you NOT importing the video. I believe the code I provided will work, but you need to reset the inBound variable at the start of each frame actionscript line for it to work the remaining videos.

Like silentweed mentioned, it would be beneficial to import the video using code all on the same frame, this way the same code is used over and over again.
