I found that if I use layer mask reflection code works correctly
http://www.natavi.co.uk/test/video_perspective.html
If I try to use script mask over my video clip
var videoMaska=this.createEmptyMovieClip("videoMaska",100);
videoMaska._x=myVideo_mc._x;
videoMaska._y=myVideo_mc._y;
drawShapeMask(videoMaska, 0, 0, myVideo_mc._width,myVideo_mc._height);
myVideo_mc.setMask(videoMaska);
Result is wrong
