This is just a little piece of code for using a SMIL file as the source of the FLVPlayback component in Flash. This is AS3 code but it is pretty much the same for AS2.
bq. import fl.video.FLVPlayback;
var player:FLVPlayback = new FLVPlayback();
player.source = “my.smil”;
“For more information on SMIL read LiveDocs”:http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00000588.html.
