In case you missed a previous post I had, here’s a tool that will install into Internet Explorer 6.02/7.0 and will allow you to simply browse to a YouTube or Google Video page and start downloading the video to your system in the form of a .FLV (Flash Video) file.
It will then in the background, kick off a conversion process that will take the .FLV file and convert it to a .WMV (Windows Media video) file which can be easily played back locally on your Windows PC, your Windows Mobile device, or your Zune.
The tool is called "Zune It" and is immensely cool. It’s been upgraded recently to make allowances for recent changes in YouTube’s interface.
