saving YouTube videos?????

Whats up everyone, i was wondering if there is any way to save or download videos from youtube or other sites like youtube to your computer. I have a bunch of videos that i like on there, and google video that i want to save onto my computer so i can make a DVD and just be able to load it when i want. Is there a program or anything i can use that will allow me to save/download the vidoes off web sites?

Do a google search for 'save youtube videos' and you will get a couple more

Then search for 'convert flv avi' to find some links to download software that will convert it to the right format (youtube is Flash Video format)

Oh man thats cool! thanks. ill have to try this out. i did do a search before, but i didnt come up with anything usefull... i guess i just didnt search for the right thing. thanks again
