This is really strange. I have a custom FLVPlayback skin that I modified after loading the fla file. I published the .swf and placed it in the relative directory. I double checked to ensure that the assignment of the customeSkin.swf is the same as the actual customeSkin.swf.
When I load the customeSkin.swf from my directory, is shows the changes. When I test the .fla that is using the customeSkin.swf, I still see the default colors. This leads me to believe that there is something wrong with the code in the .fla that is loading the customeSkin.swf.
video.skin = "customeSkin.swf"; // assignment of the custom skin
any ideas?
