Options to renew service contract, keeping cablecard?

I'm a longtime customer whose contract expiration is coming up in a month or so.  I'd like to keep pretty much the exact same service.  I'm willing to sign up for another 1-2 year contract if it will save me some money on the monthly bill.

The important thing is I need to keep my cablecard and the service it provides.  The online option I'm looking at requires I return it, and there's no way I am going to do that as it's integrated into my home theater setup.  That online service is the X1 Saver Pro+ Double Play, listed at $79.99/month.

How can I go about getting another renewal that will allow me to keep the same service, with the cablecard?
