While following this very long and complicated tutorial, I did exactly what was written. Halfway through, there was a problem - first, a link was dead, then, when I searched and found the file I needed at Sourceforge, and tried to put it in the directory indicated, I was refused "write" access in this directory.
In the terminal, there were error messages, saying packages were not there, and it had failed to install. I had to give up at that point. So now, my computer is screwed up, with this installation half done.
IMHO this tutorial is not suitable for novice users. Even intermediate users would struggle with it.
It wasn't any use to me, anyway. | 
Every once in a while, you may come across some videos on YouTube-the popular free video sharing service. You may enjoy the videos more or less but sometimes, just sometimes, you come across a video you really need to have on your hard drive and to watch over and over again, every time you feel the need. Unfortunately, YouTube seems to discourage its users from downloading the videos. This can get rather annoying because you'll need to save a bookmark with the video url, load it in your browser every time you want to re-watch it, wait until it's loaded and so on. So why get through all this trouble, when you can easily download the file in Flash Video format (FLV), convert it into mpeg4 or xvid video with mp3 audio and watch it on your PC or even on your mobile phone?
