this issue is more commonly caused by noise interference coming from the cable lines inside your house. I wander if they hooked up a spectrum analyzer to your house wiring to test for that. I've had all brand new wire and one tv's tuner picking up some over the air radio stations and back feeding it onto the cable wires causing the picture the break up and if the noise is in the line then putting in a amp with make the issue worse. They need to test your house for noise issues.
try a cable amplifier. i got mine at Wall-mart. it still does that thing but just not all the time now.
i had the same problem, Comcast started charging per a TV, even a direct connection with out the cable box. i think its like $3.00 over hear. any way people just don't tell Comcast about the extra TV's on there system. Comcast regulates how strong of a signal they give you so if someone is useing a extra TV, even down the block, it could end-up with that.

"any way people just don't tell Comcast about the extra TV's on there system."
Ok and these same people probably complain when the tv starts acting up cuz of the weak signal going to it
"Comcast regulates how strong of a signal they give you so if someone is useing a extra TV, even down the block, it could end-up with that."
What? This makes no sense.
Yea we have a system to distribute the cable based on length of the drop. If you need more signal we install an amplifier, it's that simple.
