When they installed mine,(10 years ago) They ran 1 new line to a room .
asked him to run another line, he said it would cost like 100 $ because it was too far away, So then he used all old existing lines from cable, which are now no more good.(Weathered and do not work at all when very wet)
So when I called them about it, said it would cost me $ to replace any non working lines. Well I just have given up with them.
I will be getting new lines from Videotron, and will maybe keep a bit of SC on the one TV. for the time shift stuff, but only bare essentials. but may just cancel if I am happy with Videotrons HD Quality.
