XVE (XVE Various Embed) is a simple yet powerful way to add media content to your WordPress blog. It is a drop-in replacement for my old XHTML Video Embed plug-in, while it aims to continue the original support.
The plug-in is self documented, so there’s the point where you may want to start. The help is integrated into the WordPress help system. If you’re looking for it, it’s into the above menu, the ‘Help’ item. For some of you, this isn’t so obvious as the Help system is kinda new.
New features and support requests are honored better if you open a <a href="https://github.com/SaltwaterC/XVE-Various-Embed" title="GitHub" rel="nofollow ugc">ticket on GitHub</a> where this plug-in is actually hosted.
Supported video services: youtube.com (youtu.be URLs as well), metacafe.com, dailymotion.com, revver.com, spike.com, vimeo.com, livestream.com, capped.tv, trilulilu.ro, 220.ro, collegehumor.com, myvideo.de, snotr.com, gametrailers.com, blip.tv
Supported audio services: trilulilu.ro, 220.ro
Supported image services: trilulilu.ro
It also supports generic SWF / FLV (MP4) embedding.
For the FLV (MP4) embedding, there are three provided players: Flowplayer, FLV Player, and JW Player. You may change them on the fly without the need to change the embed code.

Allows templates to serve XHTML5 markup by adding the necessary JavaScript shim for IE7+, and for IE6 by converting all new elements to <code>div</code>s and <code>span</code>s with class names that contain the original HTML5 element name prefixed by “<code>html5-</code>“, for example: <code><article></code> becomes <code><div class="html5-article"></code> 
and <code><time></code> becomes <code></code>
If the browser supports XHTML, the content is served with the <code>application/xhtml+xml</code> 
MIME type. This can be disabled by placing <code>remove_filter('option_html_type', 'xhtml5support_filter_html_type')</code> 
in <code>functions.php</code>.
Note that print stylesheets do not get applied to IE7+ even with the shim, so if you are relying on the ability for IE users to print properly-styled pages, you must force the IE6 renaming behavior for all versions of IE by doing <code>update_option('xhtml_support_add_msie_shims', false);</code>
