Update, I think it's an issue with something in one of the encrypted files.

I just tried 3 other video packages (that all use ffmpeg-php) and they all work with no problem. Also I confirmed that ffmpeg-php is (obviously) on the server (or the other packages would not have worked).

Also, I found out that the ffmeg-php is not called 'ffmpeg_movie' which is part of the error message (Fatal error: Class 'ffmpeg_movie' not found in /home/xxxxxx/public_html/include/functions_upload.php on line 175) instead it's just ffmpeg.

Anyone have a fix?
