How to save Youtube Files and Convert them

Reading the title makes me think I am some kind of evangelist. I seriously get annoyed when we do a google search for something like that and get no step-by-step information for this. Me being technical can figure it out if I really want to. But wonder how much trouble someone less associated with the computer's million types of configurations.

Ok, so this old friend of mine has her assignment and part of it is to submit a video file which was on youtube. How to save them:

1. Make sure you are using Firefox to watch the video. Get it from here - http://www.mozilla.com/firefox/ . There is a reason for this IE downloads your video twice.
2. Copy the link of the video (e.g http://www.youtube.com/watch?v=EkTpUxh8Vxc) from the address bar of Firefox.
   
3. Paste the link in this site http://www.youtubex.com and click on download. Now if you were using Firefox to watch the video and then click on download the download is instantaneous. But if you were using Internet Explorer the video downloads again. It has downloaded before when you were watching it.
   
4. Once the file is downloaded, rename it with .flv extension.
   
5. There are quite a few softwares to convert a flv file to mpeg or other video formats, but I found Total Video Converter good for this. Get it at http://www.effectmatrix.com/ and install it.
   
6. Once you got the software it is very easy to select as it is very user friendly to select source and destination files.
   
7. Don't forget to ask for favours from your friend in return..
   

Hope that helps.
