EditStudio 3 can do the conversion for you. The program itself is a demo, but the support tools (which includes a DV file type converter) are a free addition that you can leave installed once the demo times out.

I decided to post the links instead of going into a lengthy explanation to conserve bandwidth for Baldrick

On a side note, my Sony DVMC-DA1 captures DV into Type 2 format to begin with.
