How can I autoplay a .flv video on Screencast?

Screencast provided this code to me...

Code:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="480" height="320"> 
<param name="movie" value="http://content.screencast.com/flvplayer.swf"></param> 
<param name="quality" value="high"></param> 
<param name="bgcolor" value="#FFFFFF"></param> 
<param name="flashVars" value="thumb=http://content.screencast.com/media/4785e5fb-da30-4889-a58d-9d4b2ad9fabd_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_Thumbnail.gif&content=http://content.screencast.com/media/22e9f2fa-f976-4231-821b-bdbe694ccc6a_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_VU.flv&width=480&height=320"></param> 
<param name="allowFullScreen" value="true"></param> 
<param name="scale" value="showall"></param> 
<param name="allowScriptAccess" value="always"></param>  
<embed src="http://content.screencast.com/flvplayer.swf" quality="high" bgcolor="#FFFFFF" width="480" height="320" type="application/x-shockwave-flash" allowScriptAccess="always" flashVars="thumb=http://content.screencast.com/media/4785e5fb-da30-4889-a58d-9d4b2ad9fabd_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_Thumbnail.gif&content=http://content.screencast.com/media/22e9f2fa-f976-4231-821b-bdbe694ccc6a_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_VU.flv&width=480&height=320" allowFullScreen="true" scale="showall"></embed> 
</object>
I would prefer the video to autoplay, but when I asked Screencast support they replied...

"Unfortunately, editing the embed code is out of our scope of support. If you have any other questions about the service, please let me know."

I tried this code... but it doesn't autoplay either...

Code:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="480" height="320"> 
<param name="movie" value="http://content.screencast.com/flvplayer.swf"></param>
<PARAM NAME="PLAY" VALUE="true"></param> 
<param name="quality" value="high"></param> 
<param name="bgcolor" value="#FFFFFF"></param> 
<param name="flashVars" value="thumb=http://content.screencast.com/media/4785e5fb-da30-4889-a58d-9d4b2ad9fabd_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_Thumbnail.gif&content=http://content.screencast.com/media/22e9f2fa-f976-4231-821b-bdbe694ccc6a_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_VU.flv&width=480&height=320&autostart=true&autoPlay=true"></param> 
<param name="allowFullScreen" value="true"></param> 
<param name="scale" value="showall"></param> 
<param name="allowScriptAccess" value="always"></param>  
<embed src="http://content.screencast.com/flvplayer.swf" width="480" height="320" quality="high" bgcolor="#FFFFFF" type="application/x-shockwave-flash" allowScriptAccess="always" flashVars="thumb=http://content.screencast.com/media/4785e5fb-da30-4889-a58d-9d4b2ad9fabd_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_Thumbnail.gif&content=http://content.screencast.com/media/22e9f2fa-f976-4231-821b-bdbe694ccc6a_3444fb3b-a67a-440d-937a-aa3d6e779ca2_static_0_0_VU.flv&width=480&height=320&autostart=true&autoPlay=true" allowFullScreen="true" scale="showall" play="true"></embed> 
</object>
Code #1 works, it just doesn't autoplay. Code #2 is what I tried to change it so it autoplays... it also works, but also doesn't autoplay.

The reason I want the video to autoplay is because from split testing I noticed a higher conversion on the page if the video autoplays. I tested this using Revver video. The downside of Revver is that they advertise on the video and that again reduces the conversion of visitors to sales. That's why I switched to Screencast.

Any tips on how I gt get the video to autoplay on page load?
