It depends. For instance, you could plug it in through S-Video and then use your cable box remote to change channels.
Hmm, would digital cable be QAM? If so, then you'd probably need a tuner that can do that (I don't think the AIW or other analog tuners can decode the signal properly).
If it is QAM and you plug it into your AIW through coax, you'll probably end up with it just decoding the non-digital but basic or possibly extended (or whatever your cable company calls it) channels, and so you won't be getting it digitally (and possibly with much fewer channels).
