I am trying to rip video news broadcast from a radio station using a firefox plugin 'video downloader'. It works for a serveral videos but now, I came across one that shows a 30 seconds commercial before the actual content. The 'video downloader' is only able to detect that 30-seconds ad commercial and not actual video. Whats the easiest way to rip this? Thanks. Please note that the video is not hosted on youtube.
