There is a link from the site I mentioned earlier that gives a review on Pinnacle Studio.See it here

Part of it would suggest to me that you are paying for something that you dont want/need as it is for adding stuff from analogue tapes to your PC,unless you need this feature I think you would probably find a cheaper option by getting a PCI card with TV in and connecting that way assuming your DV Camcorder has suitable outputs.What outputs has it?
Then you could get the cheaper software instead of the full package,you may even have usb out which would mean that you wouldnt need any additional cards
The part of the review that I formed this opinion from is this bit :
Introduction
Where this all-in-box package compares with the much cheaper digital-only Studio DV package (which includes Pinnacle's Studio 7 capture and editing software), is that the Pinnacle card allows the conversion of the incoming analogue signal to a DV-compatible file format. This allows users to mix analogue footage with material captured from a DV or Digital-8 camcorder using the bundled Studio 7 editing software. Thanks to the supplied breakout box and multi-pin cable connector, there's no need to make all connections direct to the computer, enabling instead the S-video / analogue / audio connections to be made from any point within 2 metres distance. Couple these features with the Pinnacle Express disk authoring and burning program, and you have what could well be the ideal all-in solution.
