As it turned out, we never plugged the cable into the TV, we have lived in the same house for 3 years and neither of us ever watched cable TV during that time. (we do have a cable subscription because where we live you can't get cable internet without the TV and radio part attached...)
I never understood why someone would pay a ridiculous amount of money (compared to say netflix) for a cable subscription and still think it's OK to be watching to ads for 25% of the time...
It's time for cable companies to accept the truth: their technology and business model is old fashioned (a free harddisk record to "pause" TV is a solution to a problem that should not exist!).
