WebVideoCap allows you to capture .FLV (Flash Video) files and RTSP/MMS video streams while the Web browser download and play them inside a Web page. After the entire video file is downloaded and played by the Web browser, the video file is saved in the folder that you selected, and you can play it offline later with any Video player. WebVideoCap can capture the video files of most popular video-sharing sites, including YouTube, Google Video, Yahoo Video, iFilm, Metacafe, Putfile etc.
Note that you can use WebVideoCap under Windows Vista with SP1, but you must download and install the WinPcap driver, and select the WinPcap driver as the capture method, so it is functional but not portable.
