From the search engines' perspective, a solution to this would be to add a "canonical" meta-tag to the page. That way, no matter what URL brought the visitor to the page, the meta-tag will tell the search engines that the original content resides at the URL you want it under.

For your example, the tag might be:
<link rel="canonical" href="http://www.mydomaine.com/xNews/article.1/my-test.htm" />

A module to "embed" videos on pages and have an XML video sitemap file created. (Helps to list the site's pages as the source of the video rather than YouTube or other video-sharing site.)
