I read this in Norway’s biggest (or second biggest (don’t know which)) newspaper some time ago. I have earlier saved youtube videos by using freeware like DVDvideoSoft to convert directly from youtube to iPod or other formats. But this seemed like a real easy solution. I don’t know how popular it is, but I had never heard of it before. The article is in *cough cough* Norwegian, but the synopsis is quite easy…
1. Find the URL / address for whatever youtube video you want to save
2. replace “youtube” in the address with “kickyoutube”.
3. Pick the format you want and save it.
