Thread:Extension talk:Video/PHP Fatal Error on MW 1.18 when viewing category: pages/reply (9)

Ran into the same issue with MediaWiki 1.19.0.

It seems the addVideo function isn't working, I was able to work around the issue with the change:

--- a/Video/VideoPage.php +++ b/Video/VideoPage.php @@ -430,7 +430,7 -                              $this->addVideo( $title, $x->cl_sortkey, $x->page_len ); +                              $this->addSubcategory( $title, $x->cl_sortkey, $x->page_len );
