Videoplayer memory problem

Hello,
I’ve been working recently with Flashdevelop trying to make a decent video player.
I have put multiple video files in to an array and set them on a loop
so that each time it plays different file.
It all worked pretty well until I’ve checked memory monitor and
I found out that player is step-using more and more memory with each video change.

I couldn’t help but notice that my player is creating multiple instances of the same looped objects. I thought that once these files are cached there wont be such problem but i was wrong.
does anyone have a clue?
