cfmediaplayer tag not working in enterprise edition

[OCBCIL]

We're running ColdFusion 9,0,0,251028 Enterprise Edition.  Each of our servers has two instances of CF running on them... and we've just determined that cfmediaplayer does not work properly in this environment.  We are testing with a simple cfmediaplayer example (below).  It does not work using a standard url... but if we specify one of the two CF instances individually, with the port number in the url, it does work.

    <cfmediaplayer name="flvPlayer2"
            controlbar="true"
            source="http://helpexamples.com/flash/video/caption_video.flv"
            autoPlay="true" />

I.e., calling this example like http://[serverName]/mediaPlayer.cfm does not work, nothing ever loads, no javascript errors, not messages of any kind... but if we call it like http://[serverName]:9300/mediaPlayer.cfm or http://[serverName]:9301/mediaPlayer.cfm... either one of those works fine.  Why is this?  Is there any way you can think of to get this to work without having to specify the port in the url???  Thanks.

Try upgrading to CF 9.0.1, in the update release notes it states:

FLV MIME type is not registered by   default in the IIS web server. Therefore, cfmediaplayer might not work.
