Anyway, back to reality... It should be noted that in the terms and conditions for service, in most states, you agree to only tune in the channels you're paying for. Having said that, just don't get used to getting channels you're not paying for: They could go away at anytime, without notice, and you'd have no reason to be aggrieved.
There are no published listings of QAM channel map assignments. The law requires service providers to offer cable converter boxes (which I assume the OP has declined) or CableCARD (which I assume the OP doesn't have use for) to map the QAM frequency allocations to the more familiar cable channel numbers you see the cable company publish lists for.
