[support] How to embed video in a story?

[AM Concepcion]

Hi, I have a Drupal 6.1 web site; mainly a blog, that recently went 
live with the help of a developer. I'm still learning my way around 
it. (I'm much more familiar w/WordPress.)

How do I embed a video in a story?  I tried ... made sure input 
method was set to Full HTML ... but when I paste in my embed code, it 
doesn't work.

-- If I paste it into the HTML (source) window, when I click Update, 
the code disappears from the edit story window. (If I open the HTML 
window again, the code is gone).

-- I paste it directly into the TinyMCE window, it appears as text in 
the published story

Do I need a module? Does it make a diff. that I'm not using 
CCK/Views, but using Taxonomy (site was originally developed for v4).

Everything else works great on the site.

Here's the embed code if it makes a diff:
<object width="425" height="256"><param name="movie" 
value="http://images.tv.adobe.com//swf/player.swf"></param><param 
name="allowFullScreen" value="true"></param><param 
name="allowscriptaccess" value="always"></param><param 
name="FlashVars" 
value="fileID=2204&context=146&embeded=true&environment=production"></param><embed 
src="http://images.tv.adobe.com//swf/player.swf" 
flashvars="fileID=2204&context=146&embeded=true&environment=production" 
type="application/x-shockwave-flash" allowscriptaccess="always" 
allowfullscreen="true" width="425" height="256"></embed></object>

thanks!
