Problem With Converting You Tube to MP3

Hi guys....I actually have figured out HOW to do this using vixy.net. It converts just fine except for one thing..when I import it to my I Tunes..a 5 minute song will say it is 45 minutes long. I have goneinto properties and tried to manually change the length of time, but it does not work. Am I missing a step somewhere? Has anyone ever used this vixy.net? It took me a few months to figure out, and I was so excited this morning when I finally did because most of what I want I can't find at the free Limewire. Then I saw what happened when importing and almost cried. I would appreciate any suggestions SO very much..thank you...Cathy:confused
