For "3) Tuner:" I believe it should be "Digital".

I believe "Analog" would be used if you were using an over-the-air antenna. If you have a combo card, one cable connection would be for an antenna, the other would be for a cable. You're supposed to be able to record 2 shows at the same time by using the antenna for one analog show and the cable for one digital show.
Being your cable should be carrying both analog and digital signals, I think you should be able to split your cable and have one going to the analog connection( and set it up as an analog tuner) and the other going to your digital connection( setup as a digital tuner). That way you could record an analog channel and a digital channel at the same time.
