attaching to video port in VB6

I am using Pinnacle Systems 9.?? & Movie Box USB
This box connects via USB to my laptop. I had used a WIN TV card by Hauppage on another system and managed to get some code to access the 3 video inputs, poll them, and save pics. Well I lost the code and the system but now I want to do the same thing using the input from the movie box. Does anyony have an idea how to grab the video from the USB using pinnacle and the box with VB6??
