I am downloading some free tutorial videos from the iTunes store each of which is around 700MB. I am on slow internet connection and whenever the download fails, if i start it again it starts from 0 Bytes instead of resuming from the point it stopped. 
Is there a way by which I can resume the downloads using iTunes or any other application??
I am using
Mac OS X 10.6.4
and iTunes 10.0.1
