Problem with embedded media and IE8 (Youtube)

Hi, I've found a problem with embedded Youtube clips and IE8. The problem occures in all themes but the Mobile theme and the browser states the following:

Webpage error details

Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)

I checked earlier posts in my blog (posted with BE 1.3) and found that they did not have the same problem. If I remember right the old clips where posted using a "embedded media" buttun, that button is not present in BE 1.5.

There are some significant differences in the code from BE 1.3 and BE 1.5:

BE 1.3 Youtube clip (posted with embedded media button in editor): Gives no error!

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase=",0,40,0" width="480" height="344">
<param name="width" value="480" />
<param name="height" value="344" />
<param name="allowfullscreen" value="true" />
<param name="allowscriptaccess" value="always" />
<param name="src" value=";hl=sv&amp;fs=1" />
<embed type="application/x-shockwave-flash" width="480" height="344" allowfullscreen="true" allowscriptaccess="always" src=";hl=sv&amp;fs=1"></embed></object>

BE 1.5 Youtube clip (pasted as raw HTML since embedded media button is missing): Gives error in IE 8 with all other themes than Mobile!

<object width="480" height="385">
<param name="movie" value=""></param>
<param name="allowFullScreen" value="true"></param>
<embed src= type = "application/x-shockwave-flash" width="480" height="385" allowfullscreen="true"></embed>

Any ideas?

And tnx for the best blog engine ever!

Are you using youtube extension or just copy html snippet in the post? If later, try to use extension instead.

The problem was a combinatin of lightbox and youtube clips. I disabled lightbox and the errors are gone!
