IE7 and Multiple Embedded SWF Videos Not Working

Question

We have a page that contains 2 videos that are streamed from our media hosting company.  The code is fairly straightforward,
<object type="application/x-shockwave-flash" data="http://xxx.xxx.xxx/your.swf" width="400" height="300">
<param name="movie" value=http://xxx.xxx.xxx/your.swf"" />
<param name="allowFullScreen" value="true" />
<param name="wmode" value="transparent" />
<param name="allowScriptAccess" value="always" />
<param name="flashvars" value="streamer=rtmp://zzz.zzz.zzz/zzz.flv&autoplay=false" />
</object>
Similar code is used for the second video. The embed code is actually generated from the hosting company and has worked every time. Firefox and Chrome display both videos with no problem. However, IE7 only displays the second video. The first video just has white space where the video should be.
I have used 'embed' tag and conditional object tags (for IE), rewritten the code from scratch, changed the z-index, used Flash to generate code, cleared the cache - all to no avail. Is IE7 incapable of having multiple SWF files on the same page?
**I did notice that changing the autoplay attribute to true will allow for the video to display, however, the playback controls are not available.
Any ideas on how to get this working in IE7?
Thanks in advance

Another me too. In particular the symptoms are this:
+ any YouTube video embedded within a webpage loads the poster frame and the controls, but after clicking the play button only shows the progress indicator briefly before showing "An error occurred, please try again later." within the video frame.
+ the same YouTube videos play fine on the YouTube site.
+ other Internet video plays fine, embedded or not.
+ when the error occurs Safari reports "One error in opening the page. For more information, choose Window > Activity".
+ the Activity window shows "forbidden" for http://v13.lscache4.c.youtube.com/videoplayback?ip=0.0.0.0&sparams=id%2Cexpire%2 Cip%2Cipbits%2Citag%2Calgorithm%2Cburst%2Cfactor%2Coc%3AU0dWSVhMVV9FSkNNNl9QRllH &fexp=900028&algorithm=throttle-factor&itag=34&ipbits=0&burst=40&sver=3&expire=1 274817600&key=yt1&signature=C15947474FA80C9A1B9DA597103C5FF7D621A478.0C1490DE456 5D519F602B0043A4E1F9D800417A0&factor=1.25&id=c3e8886e8b459334
+ the same URL downloads fine when visiting YouTube directly, except the signature value is different.
I have tested the following:
+ the same computer worked fine a week or so ago
+ other computers on the same shared ADSL connection work fine
+ Firefox works fine (contrary to other's experiences)
+ deleting com.apple.Safari.plist doesn't help
+ disabling/enabling the "Enable Plug-ins" preference doesn't help
+ deleting Preferences/Macromedia folder doesn't help
+ reinstalling Flash doesn't help
+ empty cache doesn't help
Tis quite perplexing.
