the problem seems to be that i cant take a instance of the BitmapClass of a .FLV [flv playback] bicouse i try the same thing with the webcama nd importig a video [.avi] ad t works fine. Why is ot workng with .flv ?

this is where i think the erorhappe: bmd.draw(vid)

where vid is a FLVplayback componet of Player8
