Here is another useful program. This goes under the extra software category because it isn't really a computer security program. However, it does something that many people are looking to do these days.
This program is called Video Piggy. Basically, this program lets you download videos off YouTube. YouTube has yet to add a download option to videos on their site, so this program is VERY useful. There are free ways to download videos off YouTube, but you end up having them saved as .FLV files. Theres not a lot you can do with that file format. With this program, you can download YouTube videos AND convert them to various file formats. This means you can convert videos you download on YouTube so they play in Windows Media Player or other Video Players you may use. This program can also extract the soundtrack of the video to an MP3 player. And also what I think is the coolest feature, this program lets you convert videos so that you can play them on your iPod, Zune, Sony PSP, etc.
In wrapping this up, I must say, this is a very useful program if you love to browse YouTube (like me!). I highly recommend this software.
Here is the link.
Update: The link appears to be down. If you are looking for a YouTube downloader, check out my review of TubeTilla Pro. It is a very similar program.
