Problem getting embedded flash to play

I uploaded a folder containing …

oil-spill-dome.html
oil-spill-dome.mp4
oil-spill-dome_controller.swf
FirstFrame.png
expressInstall.swf
swfobject.js

The plug-in https://www.mac-dev.net/blog/files/flash-video-player.5.0.4.zip says

3. Add video to your posts using the following tag:

[flashvideo file=videos/my-video.flv /] *

I tried

[flashvideo file=videos/https://www.ourchangingglobe.com/video/oil-spill-dome/oil-spill-dome.mp4 /]

and it loaded but said, “video not found or access denied”.

The author of the plug-in suggests in his FAQ

Create a new text file named crossdomain.xml.
Open crossdomain.xml in a text editor.
Add the following XML code to the file:

<?xml version=”1.0″?>
<!DOCTYPE cross-domain-policy
SYSTEM “https://www.macromedia.com/xml/dtds/cross-domain-policy.dtd”&gt;
<cross-domain-policy>
<allow-access-from domain=”www.yoursite.com” />
<allow-access-from domain=”yoursite.com” />
</cross-domain-policy>

Save the file.
Upload the file to the root directory of yoursite.com (so that the file can be accessed at https://www.yoursite.com/crossdomain.xml).

I did this but when I click on the link I get a parsing error.

XML Parsing Error: not well-formed
Location: https://www.ourchangingglobe.com/crossdomain.xml
Line Number 1, Column 1:{\rtf1\ansi\ansicpg1252\deff0\deflang2057{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
^

Any help would be much appreciated.

P.S. This does work …
