Steps to reproduce:

 1) Click this link:

 http://api.addthis.com/oexchange/0.8/forward/myspace/offer?url=http://www.nbc.com/heroes/video/clips/brave-new-world/1199942/&title=Brave%20New%20World&description=In%20the%20season%20finale%2C%20the%20heroes%20race%20to%20thwart%20Samuel%27s%20vengeful%20plan%20to%20kill%20thousands%20of%20innocent%20people%20in%20Central%20Park.%20Volume%20Six%3A%20Brave%20New%20World%20begins.&swfurl=http%3A//widget.nbc.com/videos/nbcshort_at.swf%3FwidID%3D4727a250e66f9723%26clipID%3D1199942%26showID%3D51%26siteurl%3http://www.nbc.com/heroes/video/clips/brave-new-world/1199942/%26domain%3Dwww.myspace.com&height=283&width=384&screenshot=http%3A//video.nbcuni.com/player/mezzanine/image.php%3Fw%3D512%26h%3D288%26path%3Dnbcrewind2/b02b1d62039c04f40089cc5e73681f32_mezzn.jpg%26hash%3Dce54b672b0e1109fa11d4b8b446a2097

(copy and paste entire link into BROWSER)

The content in RED represents the SWF URL. It has the following query string params appended after nbcshort_at.swf --  widID, clipID, showID, siteurl, and domain.

 
2) Share it to your profile

3) View it

4) Click the "Play" button

5) The embedded content won't play. If you inspect the embed code with Firebug, you'll see the following: 

<embed height="297" width="350" wmode="transparent" src="http://widget.nbc.com/videos/nbcshort_at.swf?widID=4727a250e66f9723" allownetworking="internal" allowscriptaccess="never" type="application/x-shockwave-flash">

 Notice that the source only has the "widID" param. If you replace the source entirely with the above marked "red", it will play the video (url-decoded where necessary).

When l click on this I immediately get the "missing required width parameter" error from your site.

Please also read about the video param meta tags in our Share on Myspace document here. You need to define them in this way:

Notice the discussion of multimedia meta tags:

<meta name="medium" content="video" />
<link rel="video_src" href="VIDEO_SOURCE_URL_GOES_HERE" />
<meta name="video_height" content="VIDEO_HEIGHT_GOES_HERE" />
<meta name="video_width" content="VIDEO_WIDTH_GOES_HERE" />
<meta name="video_type" content="application/x-shockwave-flash" />

thanks,

Thanks for the reply Joel. We're actually aware of the multimedia tags, and suggested that, unfortunately, it's not possible in this case.

Are you guys aware of the issue though with multiple query string params? Is it something that will eventually be fixed?

 As with the other thread, we're discussing this via email and will get back to you once we have a solution.

thanks,

Joel

 We had a code roll issue, but this issue with sharing will be corrected before the end of the week. This is still the problem you're having, right?

thanks,

Joel
