Update
As stated at the start of this thread: we were kicked out of Google search results for over 1 month; because Google serps was prepending the date our blog was started: Jan 23, 2009 - to the start of our meta description.
Even AFTER implementing the above changes; as soon as I activate Yoast plugin: WP SEO Video, Google starts showing that #$%@ date again! (and we are dumped a page or two back in the search results - AGAIN)
Joost if you are reading this: I submitted a support request for this PAID plugin and got this reply:
Hi Les,
I'll forward this to Joost again then, but it might be some time before he answers due to holidays and workload :)
Kind regards,

I have since added the following code to my functions.php file:
add_filter( 'wpseo_video_show_date_in_snippet','__return_false');
If this code does not work, I will have no option but permanently disable WP SEO Video.
This plugin is supposed to help your SEO - not stuff your rankings!
