Describing several video in the same page

Hello,

I try to describe several video in a same html page, but does not get a
proper results from rich snippets testing tool.

It works fine with a single video :
http://www.google.com/webmasters/tools/richsnippets?url=http%3A%2F%2Fjean.delahousse.free.fr%2Fexemple-multi-video-page-V2.html&view=
but results with 2 video is the following  :
http://jean.delahousse.free.fr/exemple-multi-video-page-V1.html  with an
error message "This page does not contain authorship or rich snippet
markup." and an empty preview

Does someone has an answer to this point ?

Thanks
Jean
