[Plugin: Video Thumbnails] checking past post

Hello,

(sorry for bad english)
I use WP 3.4.2 and Theme “Videoplus”

I’ve install video thumbnail succefully on my theme to have a thumb of the video using the Facebook share for my post.

Video thumbnail works perfectly but when I try to check all past post and save it in the “media” it scans all my post (500) sucssefully, but I can only find 74 thumb in my media library.

So the share function on Facebook with the good thumb works only for these 74 post but not for the others.

Maybe somoene can help me to find solution to have a saved thumb of all my post.

Thank you.

Constantin.
