I agree with your diagnosis, the issue is where is the signal loss being intoduced into the system. I was trying to guage the extent of the problem by asking if anyone else was having problems. Looks like others are not having the same problem based on the number if responses I received. Now I have to track down the culprit. I have already eliminated the home wiring by running the TV directly off the TWC tap with three different RG6 cables. I hope TWC is able to quickly find the issue on their end. Since I am in a new subdivision I am getting the run around with tech support. I finally talked with someone today who is trying to expedite the issue. I will let you know the results.
I had a similiar issue with my subdivision (now 5yrs old and mine was the 10th house built.) I brought a portable Spectrum Analyzer home from work and I could see that the channels I was having problems with were either lower power than neighboring channels but TWC wasn't willing to do anything about it. Sometimes it was good enough to work and sometimes it wasn't, but it was always the same channels that failed which were underpowered.
Initially the cable guy was going to put a booster in, but his boss told him not too as the power level on the meter indicated it was good and instead they removed my 8 way splitter and put a 2-way (pull cable modem off first) then a 3 way (for only three rooms)
Later I bought a 15dB signal booster for about $40 (Motorola brand) http://broadband.motorola.com/consum...er/default.asp
And put my 8-way splitter back in (which has 11dB drop) so overall I upped the power to the STB by about 13dB
+15dB(Booster)-11dB(8-way splitter)+9dB(loss from chaining 2-way -> 3-way splitter removed)
The worst part of it is, I had a Cable Guy out looking at my Cable Modem (died on me recently) and he tried to take the booster off and telling me I didn't need it with the new Cable Modem and he was going to take it with him. I had to pull out my friggin receipt to show him that it was my booster and not TWCs.
With that said, it may be beneficially to go out and buy a signal booster and see if that takes care of the problem (or at least the next time a cable guy comes out, make him put one on and see if it changes things.) I think TWC wanted something like $90 for their generic brand booster (which I wasn't going to pay for either.)
