I'm guessing you may want to connect both tuners with a splitter so you can get both the standard analog and QAM channels. I can't tell from the information I saw for your tuner card if each input has a separate function. That is, one input is for analog and the other digital (QAM). Most cable companies send clear QAM for the over-the-air networks, and often will throw in some of the digital, or HD, versions of standard analog cable channels. If you go to: hdhomerun/channels - Silicondust
and enter your ZIP CODE, it will show you what to expect from over-the-air and clear QAM where you live. The digital channel numbers and program numbers shown are what you need to set up MC7 to receive the free QAM channels.
For QAM reception, there is no processing. The recording is essentially the raw MPEG2 transport stream sent over the cable with a simple wrapper to make MC7 happy. Analog requires processing. Some tuner cards, like the ones I have, do the processing in their chip set so the PC doesn't have to. This helps a lot if you have many tuners. I have four QAM tuners and two analog. Monday nights are a busy time with lots of recordings. I never miss my favorite shows.

I do pick up some HD channels that I'm not subscribed to when I have the coaxial cable hooked to the digital tuner, why is this?
Is the video processing for TV done on the tuner or video card?
