Camtasia's Studio 7 Camtasia Recorder is cool! ! ! If you are looking for something free i recommend you using CamStudio 2
I don't understand why people not search any helpful tools on google! coz there are lots of tools available & we don't know which one will be better & easy for you.
Am using one software which convert all movie files in flv, avi, mp3, mpg, that i was found from google, you can search with vob converter to flv,
Debut is video capture software that lets you capture video files directly on a PC from a Webcam, external devices, computer screen or streaming video.
Personally I use DemoCreator for PC and ScreenFlow for MAC. I need some video editing features and plenty of putput video formats. Both of them work well, though they aren't the best.
screen capture application Camtasia Studio 6/Screenflow, or you can try AVS Video Recorder, it is free. Works a treat.
Me, Camtasia too. But I also recommend Leawo Free YouTube Downloader. I often use it to download online video.
