Flash Video Playback problem in CS4/CS5

Question

I need to put a Flash Video on my website, embedded in one of the existing html pages.
When my developer puts together a Flash Video in Flash CS4 or CS5 using ActionScript 3, the video does not play - t just keeps buffering (showing a striped appearance on the seek bar) and will not play unless I refresh the browser.
I've tried copying the code from the html page that came with the set of swf and flv files and that doesn't work either.
Just inserting the swf file into the web page like we used to do in CS3 and earlier does not wor.
I noticed that now with ActionScript 3 there is no ACRunActiveContent.js file.
Videos created using CS3 and ActionScript 2 seem to work just fine on web pages.
Wonder what i can do to use CS4 and CS5 videos and have them play on html pages?
Any ideas anyone?

Answer 1

Just to clarify:
Creating a Flash Video swf in CS5 (or even CS4) with ActionScript 3 requires the video to be embedded in the web page a bit differently than we were used to with CS3 and AS2.
While the newer versions of Flash do use a different method (using swfobject) when "Publishing" a Flash .swf, it is NOT required to do so. In fact neither swfobject nor ACRun... are required to display Flash of any version (AS1, 2, or 3) on a Web page. The simple single object method will work just fine:
<object data="path_to_file/file.swf" type="application/x-shockwave-flash" width="insert_width_of_movie" height="insert_height_of_movie">
  <param name="movie" value="path_to_file/file.swf">
  <param name="SomeOtherParam" value="ParamValue">
</object>
Both ACRun and swfobject are "Flash Detection" methods used to display some alternative content if Flash is not detected... they are NOT needed to simply display the Flash .swf.
However, you can't use half ACRun code and half swfobject code....it must be either one or the other... and either would display AS3 players just fine.... as would the single object method.
