When I insert an MP4, RoboHelp assumes the player is QuickTime - can this default be changed to Windows Media Player?

I am using RH 11, and when I insert an MP4 into an existing HTML topic, it inserts code that assumes the codebase is qtplugin.cab and the type is quicktime:

<p style="background-color: Transparent;"><object data="../TrnMedia_SHR/Retrieve a Record - Known Carrier ID.mp4"

              classid="CLSID:02bf25d5-8c17-4b23-bc80-d3488abddc6b"

              codebase="http://www.apple.com/qtactivex/qtplugin.cab"

              type="video/quicktime"

              style="border: none;">

<param name="src" value="../TrnMedia_SHR/Retrieve a Record - Known Carrier ID.mp4"

  />

<param name="autoplay" value="false"  />

<param name="autostart" value="false"  />

<param name="ShowControls" value="1"  />

<param name="controller" value="true"  />

</object></p>

Are there other player options and if so, where can I find the appropriate HTML (i.e. Where would I find the HTML code for using Windows Media Player  instead of QuickTime?)?

Thanks!
