Adding Embedded Video to Sidebar

Hey folks,

I added this code to my sidebar:

<div align="center"><img src="wp-content/graphics/logos/featurevideologo.gif"/><br /></div>
<div align="center"><embed src="https://walkernewsdownload.googlepages.com/mediaplayer.swf" width="300" height="250" type="application/x-shockwave-flash" pluginspage="https://www.macromedia.com/go/getflashplayer" flashvars="file=https://www.hometheaterloft.com/wp-content/videos/welcome.flv"/></embed></div>

It did work for about a day and then, for some reason, when I load the page, I get a white screen where the video used to be. What’s the problem?

Thanks for your help! ??
