Oh, it goes in the similar port to where you put the speaker cables. That makes a lot more sense. I'll have to try it. The thing is, the PDI card came with some cables that had the exact same RGB imputs on them. So I brought those to the store and tried the phone plug and it wouldn't fit meaning it wouldn't fit into the imputs on the capture card either. But I guess that didn't give me a good chance to see if those phone plugs would fit into another imput somewhere else on my computer.
