HI there. If you have a swf file then you could try uploading it using the "File" resource. That should work. Alternatively you could add a "page" resource and then click the media icon and add your swf file that way so it will display embedded on the page.
Many thanks for your reply. I've tried both of your suggestions but to no avail. All I get is an elaborate icon/picture showing a % indicator. Presumably indicating that a/the is loading. When it reaches 100% nothing happens. I guess something is happening, unfortunately, the video does not display.
