ExDilbert hit the big issue on the head.
Nothing will tune, even with a digital tuner for up here, as nothing is with cablecard.
All in all, best bet would be to use a tuner, which has an IR BLASTER capability, to be able to tune a digital box.
Usually those ones are a little more on the more $100+ side last I looked.
Would only be able to record SD as well, using your standard inputs (coax, composite).
Would need something like the Hauppauge HD PVR or Colossus card.
