How do you get the clearest signal from cable TV?

How do I get a digital signal from my cable box into a DTV Ant Input on my TV Tuner?

• My cable box has HDMI and Composite outputs and my TV tuner card has a DTV Ant input for OTA Digital stations. Is there a way to get a digital signal from my cable box into my Tuner Card?

• Answer:

  You can not do that, the input on your tuner card is for an analog radio frequency (rf) signal. True it is a digital signal but it is encoded to an RF format. Nor can you convert a digital baseband signal to RF easily. You have run into the same problem I have, the lack of proper AV inputs on a computer. There are cards that offer reasonable inputs and outputs but they are very expensive. It's getting more popular but real convergence is still a long ways away. If your card has a video input, an S-video input, or a component input you can use one of those possibly.
