Bill;
Cable knows what is causing the problem, which happens to be a digital pulse
they are injecting between the Ch3 and Ch4 carrier. Since this is only
effecting late model Panasonic's and Toshiba, they have decided not to do
anything at this time. In the meantime we are changing the 4.5 mhz ceramic
filter with an older version, which has corrected the problem for now, but
just wanted to know if any other areas were having problems with this.
