Imagine for a moment this situation. You found a couple of interesting video tutorials on how to do nunchaku cascades on YouTube, but you cannot download these videos to play on your iPad or iPhone in the gym. So you have to recall the movements from memory, or watch that video online and learn cascades at home, which is not very convenient because there is not enough space in your room, and you are afraid of breaking your mom's vase. Fortunately there is RealPlayer that can help you download and save YouTube videos for a portable device.

RealPlayer is a YouTube to AVI downloader that lets you extract a video from YouTube and save it to disk for offline playback. Not only does it download video to hard disk, the program also provides you with some other useful tools. You can, for example, trim a video to your format, convert to other formats using presets for different devices, and post your video to social networking websites like Facebook and Twitter.

The central part of RealPlayer is the "Download This Video" button which seamlessly integrates with the browser. It is fairly convenient because you can download video on the fly without having to step out of the browser.
