What's the format of the video clip? I don't think Asterisk supports all 
formats. And, shouldn't it be canreinvite='no'?

Should be canreinvite='yes'. This might be a bug. On the other hand, in 
your case, even if Asterisk did detected the messages. Without being in 
the media path, it still won't be able to playback video to the endpoint.
