Configure wordpress video gallery

I am looking for a Wordpress guru to configure my CVG Cool Video Gallery plugin. I am having the following troubles: - Can not find FFMPEG so thumbnails are not being generated (I do have it installed) - The add from youtube feature does not work, returns an error I just need my CVG plugin to be fully functional so I can begin using it. I need to be able to upload videos up to 1GB in size. Feel free to suggest a better video gallery if you know of one more fitting for my website, [login to view URL]
