I checked out the card and, as I remembered from memory, it only has 1/8" mini jacks. Did it come with an 1/8" to RCA dongle? If not, you'll need an adapter that can perform that function (not a 1/8" stereo to 2 RCA though) to use your digital out. Then, just use a good-quality 75 Ohm RCA-RCA cable. As mtrycrafts stated, a good video cable is just fine. However, a small generic analog interconnect may not have the 75 Ohm impedance, so use one that is designed to the correct spec.
