The first is freeware and it is called Moyea FLV Downloader. Simply download this program, copy and paste the Youtube URL into the Moyea web browser and tell it where to save the file.
The other piece is called AVS Video Converter. It can be downloaded as Shareware...I don't recall what the limitation is for this particular piece since I bought their entire suite for $59.00...it's that good. Read their website and see what you get for $59. It's amazing and their stuff WORKS. But I digress.
Use the AVS Video Converter to convert your saved Youtube FLV video to .wmv with 2 clicks of you mouse. You're done. Simple. I have done this many times and it works everytime.
The limitation is a watermark right in the middle of the converted video. So it makes the video unusable for the most part, although it allows you to see the quality of the conversion. It is a very good program if you pay for it.
