On CableCARD-equipped TiVos before Roamio, the CableCARD pairing info was stored on the hard drive. I've always made a point of paring the M-card before making my backup. That way I didn't need to call the cableCo for a re-pairing if I ever had to restore from a backup image. With the OS now in firmware on the Roamio models, does anyone know if the CableCARD pairing data are still on the HD? Or do they now store that in flash RAM or some such?
