All cable signals are encrypted now. You need the box to do tuning, and it's rf output is only going generate channel 3 or channel 4, depending on its setting. The only way to do what you are wanting is to have charter to install an MDU modulation system like they use in hospitals and hotels.
This is your only option, other than soldering the equipment buttons to the remote control.
This will get expensive, so be advised. The price is typically determined by how many channels they want available for the machines.
