How do you record Halo 3 via Diamond VC500?

[Sims Maniac]

I've been going crazy all day trying to figure out how to get my machinima clips onto the computer! It's a new Diamond VC500 capture card and I don't know what to do; I connected all the cables but all I get is a black screen! Please help me!
