Topic: AverMedia LGP lite compatible?

I'm using an Avermedia LGP lite to capture hd footage from a canon legria camcorder but kinovea doesn't pick up the feed. Is this just an incompatibility or is there a way to get the feed in? If not the Avermedia box, what is the best way to get the feed up and running?

I'm wanting to use the live feed delay to use during a rugby game so that we can re-look at incidents which occur during the game.

Thanks for any help you can give!
