I'm running Atahualpa 353 and WordPress [latest version 303].
I can NOT get Atahualpa to post a single video in my blog. I'm trying to simply take videos from YouTube and put them in my blog posts; I used to be able to do this...

I have tried the embed code; I've tried the URL and the videos just don't work anymore.

I have pasted the embed code manually and it just gets stripped from the post and converted to some crap that doesn't work.

Example
This is a working embed link:

<object width="640" height="390"><param name="movie" value="http://www.youtube.com/v/nxPB9yy7IJ4&hl=en_US&feature=player_embedded&version=3"></param><param name="allowFullScreen" value="true"></param><param name="allowScriptAccess" value="always"></param><embed src="http://www.youtube.com/v/nxPB9yy7IJ4&hl=en_US&feature=player_embedded&version=3" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="640" height="390"></embed></object>

and I save it as a draft, and preview it... And I get this from the source code:

<param name="movie" value="http://www.youtube.com/v/nxPB9yy7IJ4&amp;hl=en_US&amp;feature=player_embedded&amp;version=3"></param>

That doesn't work— There's no video, no place holder, nothing.

Is ANYONE else having this issue? Please what's the correction for this?
It has to be the theme, because I have 3 other WordPress blogs running on the same server and it worked before and it stopped working with an update, but not certain when [i don't post videos that much].

I saw another post about excerpts, I changed all those to FULL POST; nothing happened.

Thanks in advance...

Until next time,

okay, it may not be the theme; I tried 5 different themes and they all have the same issue. All the embed code gets changed... But I have other WordPress installations on the same server and they're working fine... I'm close to scrapping the whole thing and starting a new.

I'm still searching...
Thanks in advance...

Your code works for me. Are you pasting into the HTML editor view. If you paste it using the visual editor it will get messed up.

If you are pasting in the the HTML editor and it is not working I would look at one of the other plugins being the culprit.
