you need a video editing/authoring program. With minidv, your camcorder should have a ieee 1394 (firewire) port to stream the video into your computer (which needs ieee 1394 also). From there you can use a number of programs like ulead, videowave, studio8, etc.
You do not need a video capture card (unless you consider a ieee 1394 card a video capture card)
The downloaded video will be AVI. The software will convert it to a number of different formats.
found this on another forum hope it gives you the info you need
