Help with Gravity Forms & YouTube Thumbnails

Hello, I’m running a theme that I customized to work with SimpleVideoEmbedder. The site itself was initially designed to run off user-submitted content, with the help of Gravity Forms. Basically, I have the user submit a video URL with Gravity Forms with the custom field so that the URL is inserted into the SimpleVideoEmbedder plugin and then shows on the video page. All of this part works; I’m having a problem with the ‘Video Thumbnails’ plugin finding the image for a Gravity Forms post. Nothing is noticed by the plugin unless I go in and manually update the post by myself, which is a huge hassle when the site receives many (~20) new submissions daily (and it hurts the site’s appearance). Does anyone know of a way I can run a post publish function (Video Thumbnails) when I publish a post w/ Gravity Forms? Thanks! Matt
