you can embed the flash in your asp.net
Example:
Got from You tube
<object width="425" height="344">
<param name="movie" value="http://www.youtube.com/v/Xt5t9BO6xkA&hl=en&fs=1"></param>
<param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param>
<embed src="http://www.youtube.com/v/Xt5t9BO6xkA&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed>
</object>
You'd only need this:
<object width="425" height="344">
<embed src="PATH_TO_YOUR_FILE" type="application/x-shockwave-flash" width="425" height="344"></embed>
</object>
