The above link works for me?
AME is doing its thing, hence the video code looking like it is. That means AME found it as a match, went to the website and grabbed the ID (1594731) and wrapped it all up for vB4's video parser. So not too sure what to say
*edit - attached is a screenie of the video above on my test board. This is editing the message so AME has already wrapped in [video] tags and shows like yours.
HTHs
