Until today I’ve used a Greasemonkey script when I’ve wanted to download and save videos from sites like YouTube.

Not anymore.  Enter vDownloader, a freeware app that’s obscenely simple to use and works perfectly (so far).  There is no setup package – just unzip the download and start ripping! A cool feature I discovered accidentally: leave the program open and copy a video URL to your clipboard. vDownloader automagically downloads the file as generic data, prompts you for the destination file type, and then encodes the data according to your choice.  Sweet!
