Hou will need to convert it to a FCP frenfly quicktime.
However the big iset broblem that you will be facing if the quality hit that the video will take before it gets back to DVD.
You are taking an already compresed vvideo (already compressed onto DVD before) converting it and then recompressing it.
In some ways it is similer to photocopying a photo copy the end image just isnt nearly as nice.
