In case anyone is interested (if not, don't read):
Youtube has a filter that prevents showing content if it does not like your IP address.
This proxy service
http://www.gizlen.biz/ will bypass that filter. *But for gawd's sake don't use it for anything private*
FreeDownloadManager will enable you to save the content to your hard disk and convert it from .flv to .avi (or you can use FormatFactory).
