While most video recording tools are limited to the major video sites such as YouTube or DailyMotion, iTube Grabber promises to capture almost any audio and/or video stream.

iTube Grabber also instantly converts from standard FLV formats used by sites such as YouTube to several formats of your choosing such as iPod, iPhone, MP4, MPEG and even Matroska. iTube Grabber works within its own interface so all the browsing you do of video sites is done within it. When you find a video you want to download, just click the red camera button (which confusingly looks like a webcam rather than a download button) and downloading will commence.

If you've selected a conversion format to convert to in preferences, conversion takes place on-the-fly so that your video is ready for use in the format you want immediately. I like the way you can even configure the resolution you want and even the quality of the download. One downside is that there's no status indicator in the dock icon to tell you how far a download has progressed if you leave the application. Some users have also reported several instability issues in this beta version.

The developer says that iTube Grabber won't be free when it's finally released so grab this free version while you can and enjoy!
