Some famous video and TV sites like Hulu, CNN, Netflix, etc, are offering live streaming video, movie, TV shows and episodes, which don't have any actual video file there. Given this, you can't grab videos using common video grabber software. Or you are likely to be blocked if you are using a normal video downloader. Luck for you, the Advanced Video Detector of Video Grabber Pro is dedicated to downloading those protected video streams. With it, you will not miss any episodes and movies you like.
