Note that lot's of cards are coming with free software. you might not need to buy it.
When looking for a video capture /Editing card the first thing to look at is your Video camera. This will tell you what connectors you will need. Good places to look for cards are Pinnacle and Canopus.
I recomend ask some one that can also show you how to edit to help you in getting and installing a card since it's some times a problem to people that not used to work with Video cards.
Finaly,

This card have analog (RCA) connectors as well as digital DV.

It have Hardware exceleration for exporting to various formats like DVD and CD. also come with a authoring program for it.
