I did change the settings and I did get a couple to create thumbnails but not alll of them I still get this error.

$video_src = /home/religiou/public_html/video/--GodTube-Logged-In(2).flv
File found = /home/religiou/public_html/video/--GodTube-Logged-In(2).flv
thumb_folder = /home/religiou/public_html/thumb/4ca4238a0b/
/usr/bin/ffmpeg -i /home/religiou/public_html/video/--GodTube-Logged-In(2).flv
Creating Thumbnail with ffmpeg

Thumbnail created (ffmpeg)





I am still not sure on the featured video problem.
