why can't i record any of my show on to a VHS tape from my com-cast cable box anymore it worked in 2010 and stopped working in 2011 and now i can't record stuff on to a tape no more and if their is any kind of chips in the box blocking me from doing this how could i remove them or unsolder them see how i hook my cable up is the cable that comes from outside i plug it into the VCR then from their to the TV or from the box to the VCR to the TV so that i can record on to VHS tapes and when i hook it up like that now i quit getting cable channels why is this???
