Need help, looking for one video conversion tool for my BB.

A few days ago, I purchased a Blackberry Curve 8310.
I recently saw an exciting video of 2006 FIFA World Cup on Youtube, it makes me very
passionate, I downloaded it using a tool, I would like to put it on BB, but the BB only supports AVI,
MP4, 3GP, WMV formats, so need this youtube video converted into the above formats, is there a
better format conversion software?

I have seen in one friend's facebook recommending Daniusoft Video Converter for Mac, I started to play BB, do not know how to put the converted video onto my BB, I really need help, anybody can help me? Thanks in advance.
