if you go to link and put the link to a video from youtube or google video it downloads the file in .flv and then you have it on your computer so then you can view it in vlc player or just reformat it.
I use VDownloader. It works with both YouTube and Google Video and often lets you choose the format and resolution in which the file will be downloaded (I said often because that depends on the video)
I can make it easier for you m8.
Just use the Mozilla Firefox browser & get the video downloader plugin for it from Firefoxs site.Then you can get all vidz that are on the net by just ..a click
