Hello. I am a former computer technician. I am not versed in digital and satellite technology. I am seeking assistance addressing COMCAST's conversion to digital. I hope there is a cleaner installation than the one they direct. I had the same problem with AT&T when I installed DSL. One splitter in the D-mark box vs filters all over the house is much cleaner. I am hoping to do a similar installation for cable, but lack the technical expertise to implement. I have thoughts, but do not know if they are feasible. If this is the incorrect website, I apologize. Hello again, and thanks for any assistance in advance.
