The only way you can transfer Mini-DV tapes to any editing app is via a Mini-DV camera or tape deck.
If the video is transferred to a DVD there will be a slight loss in quality.
Your best bet is to beg, borrow or steal a camera.
Converting to DVD involves quality losses and the DVD format itself is of lower quality than DV.
If you wish to edit your own DV footage, I strongly suggest against the DVD conversion.
As Ian comments, get yourself a DV cam/deck and capture to FCP X in an edit friendly codec.
DVD stuff is not edit friendly, plus, if you want to edit later on, you will have to transcode the DVD back to DV or similar adding to quality loss and more handling.
