"ZuneIEPlugIn allows users to install an Internet Explorer plugin that aids in saving YouTube, GoogleVideo and SoapBox videos to [their] video folders. User can view them on WMV compatible portable devices."
ZuneIEPlugIn boasts the ability to download and convert the .flv file to .wmv - ready for the Zune. The software installs a toolbar button in Internet Explorer that allows access to one-click conversion. I have to say I'm skeptical that it would be that easy. Has anyone tried it? I'll try downloading it later, but in the meantime feel free to share any results you may have.
