DV is, as the name implies, digital, not analog.
It would be best, quality-wise at least, to not use the Canopus for DV.
The Canopus is meant more for analog formats like Hi8.
For the sake of ease of use, you can use the Canopus if you want. Or maybe your DV camera has some sort of copy-control mechanism that will require you to find some way other than digital to transfer it. Then the Canopus would come in handy.
