How to keep Views 2 RSS feed output from stripping out video, embeds, etc.?
Figured this out -- client request was to not eliminate any of the html markup (embeds, videos, emphasis tags, etc.) even though some of the RSS readers would continue to strip it out on their own. I worked through this by creating a views-view-row-rss.tpl.php for my specific view and then adding the following code in:

&lt;? 
 $index = $variables["view"]-&gt;row_index;
 $nid = $variables["view"]-&gt;result[$index]-&gt;nid;
 $node = node_load($nid);

 $teaser = check_markup($node-&gt;teaser);

 $description = "&lt;![CDATA[".$teaser."]]&gt;";

?&gt;
  &lt;item&gt;
    &lt;title&gt;&lt;?php print $title; ?&gt;&lt;/title&gt;
    &lt;link&gt;&lt;?php print $link; ?&gt;&lt;/link&gt;
    &lt;description&gt;&lt;?php print $description; ?&gt;&lt;/description&gt;
    &lt;?php print $item_elements; ?&gt;
  &lt;/item&gt;


Hope this is helpful to someone else, welcome any suggestions on improving this.
