What is the best youtube converter to my itunes?

There are plenty of tools on the web for downloading videos from YouTube and/or converting those YouTube videos to some format other than .flv.
I just want to know HOW and WHY youtube videos get removed. Like they'll say either: this video has been removed due to terms of violation, or youtube will delete the sound of the video. How does this happen???

Does it get removed right away or at any random time?
They remove the audio of the video because the sound on it is copyright,
If I put a song on THAT I DIDNT OWN It's not mine is it? it's the record company that made it. To stop youtube being sewed they remove the sound.

Hey everyone I need to know how(if I even can) put youtube vids in Myspace picture comments without a link. In other words just the vid is playable right beneath the picture being commented on in the comment box. I saw this once on a pic. Does myspace still support it? Thanks in advance for any help you can provide. :)
