CCTV/CNTV Video Downloader is a program that can download videos from many sources.
The file you obtain from the provided download source also installs an add-on for Internet Explorer and a new browser in your system. The Downloader lets you enter any URL in some popular video portals, such as YouTube, CCTV/CNTV an other twenty websites. The "Video Search" tab will let you look for the video you want to download in any of those portals. Once it founds the key you entered, it will show you a list. You can select the files you want to download from that list. The program will save the videos you selected in the quality you choose (the highest quality should not be available if you are not a VIP Member).
Once the video is saved, you will be able to view it. The program will save it in its usual format, FLV, but will also offer you to convert it to another video file format by downloading a free utility that can do it. The original video file will not have any watermark or limitation on its duration.
