Also, for those of you who like to watch videos even when you're not near an internet hotspot, there's also a program for PC called VDownloader.
The application allows users to download videos from popular sites (such as YouTube, Google Video, MySpace, etc.) into several formats, including .AVI, .MPEG, .3GP (for mobile phones), iPod Compatible, and PSP Compatible. The program also features a built in browser, so that you can search for new videos to download. VDownloader also has parental features, so that children can't access adult video sites.
