No, a cable won't do it.
The ADS puts out component (Y Pb Pr). Your TV accepts RGBHV. To convert component to RGB, you need a transcoder (just as Ron Jones previously stated). The transcoder would sit in between the ADS's output and your mit's HD input. It would provide the necessary conversion from component to RGB.
I'd verify with ADS that you can't make the ADS talk RGB (often, there are ways to do this). Also, verify that your mits can't accept component. If you're %100 sure that both of these cannot be done, then grab a transcoder. Key Digital makes a few, I believe. Search around the forum a bit.
