Displaying Categories Like Front Page

Without knowing what theme you're using it is a bit difficult to pinpoint it, but 95% of the time is because of the following:

When your blog is displaying the post in the main page it is using the function the_content() ==> This function will parse the html and show you the full content as you want to see it.

And when the post is shown in its category page your blog is using the function the_excerpt() ==> This function will strip the html and result in the problem you're having.

What you need to do is edit your archive.php in the theme folder and replace the the_excerpt() function with the_content() and that should solve your problem.
You will need to do the same for tag.php if your theme uses it... And also to your search.php

Sounds like exactly right, i will try it out,
i will PM you my Skype user so i can send you the .rar with the AS3 flash video player.
