HTML5 Player Framework - fallback to Silverlight in IE8 not working

HI I am trying to get a video to play from Azure Media services and am using the HTML5 Player Framework (https://playerframework.codeplex.com/wikipage?title=HTML5%20Player&referringTitle=Documentation)

I have tested the example on IE8 and it correctly falls back to Silverlight (http://smf.cloudapp.net/html5/html/fallback.html)

However when I try to implement my own its does not work correctly. See code snippet 1 below - It plays the HTML5 video in all compatible browsers - In IE8 it shows a black screen with a white loading icon - If I change the code and force it to play in Silverlight (see code snippet 2) then it will play in Silverlight in all browsers - These leads me to believe that the video is encoded correctly on the server

However, I notice when they have a fallback example the fallback is an MP4 but when they show Silverlight only its a smooth URL Manifest file. Not sure what is happening there. I am using dynamic packaging with Azure media services and have tried using both mp4 and mianifest

Thoughts and help please

Code Snippet 1 - Does not fallback

<video id="myVideo" class="pf-video" width="480" height="320" controls="controls" poster="../media/mdot_traderLogo.png">
        <source src="https://tradertest.blob.core.windows.net:443/asset-124e89b8-ef6a-492d-9022-30a94b9b1341/trader_H264_1900kbps_AAC_und_ch2_96kbps.mp4?sv=2012-02-12&se=2015-02-05T19%3A43%3A24Z&sr=c&si=88de031a-6525-45f1-9950-9a6015dfea8b&sig=o052OQGNcatp4zWRSeGdIPrmaJ5SfyOQm0PAw5uzT%2Fo%3D" type='video/mp4' />
        <object class="pf-silverlight" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="480" height="320" data-poster="../media/bigbuck.png">
            <param name="source" value="../xap/ProgressiveDownloadPlayer.xap" />
            <param name="onError" value="onSilverlightError" />
            <param name="onLoad" value="onSilverlightLoad" />
            <param name="minRuntimeVersion" value="4.0.50401.0" />
            <param name="autoUpgrade" value="true" />
            <param name="enableGPUAcceleration" value="true" />
            <param name="windowless" value="true" />
            <param name="InitParams" value="scriptablename=Player,autoplay=false,mediaurl=http://tradertest.origin.mediaservices.windows.net/b51f74c6-4de7-4218-94f7-2f0b8ac58358/trader.ism/manifest" />
            <div class="pf-static">
                Silverlight is not installed or a later version is required.
            </div>
        </object>
    </video>

Code snippet 2 - silverlight only - does work

<object id="myVideo4" class="pf-silverlight" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="480" height="320" data-poster="../media/bigbuck.png">
    <param name="source" value="../xap/SmoothStreamingPlayer.xap" />
<param name="onError" value="onSilverlightError" />
<param name="onLoad" value="onSilverlightLoad" />
<param name="minRuntimeVersion" value="4.0.50401.0" />
<param name="autoUpgrade" value="false" />
<param name="enableGPUAcceleration" value="true" />
<param name="windowless" value="true" />
<param name="InitParams" value="scriptablename=Player,autoplay=false,mediaurl=http://tradertest.origin.mediaservices.windows.net/b51f74c6-4de7-4218-94f7-2f0b8ac58358/trader.ism/manifest" />
    <div class="pf-static">
        Silverlight is not installed or a later version is required.
        </div>
</object>

I manage this project at Microsoft and can try to help. I'm not totally clear on your question though. To clarify, you know that when using Silverlight we default to smooth streaming but when we fall over to HTML5 we are forced to do a progressive download of the media file instead because smooth streaming is not supported, correct? Are you saying that the detection code is failing to fall back to SL when played in IE8 and is instead trying to render a video tag?
