Ok, Im still fighting the corruption issues on certain channels (FamHD only works like 1% of the time, other times it's either "off air" w/ Motorola's Overlay or scrambled.), and a few other stations do this as well (Comcast sometimes) mostly HD Channels.
So…. Time to Re-Think my strategy, replacing the splitters with Expensive ones that operate well above 1Ghz seemed to fix other channels.
Service Drop from Pole goes to top of the garage and runs down to the back, where there is the First Major Splitter. (in a water proof housing).
From there there’s 2 lines. 1 to the living room, 1 to the back room. (both travel the house's structure internally).
Line 1, to the living room, has never been replaced that I know of, and has a huge filter on it at the first splitter And that only has one DVR on the end.
Line 1 rarely has any Image problems, the occasional digital corruptions, but nothing like line 2
The huge Filter.
Line 2, to the back room, was replaced once by premium shielded cable about 10 years ago (75ft), has a Splitter attached to the end, from there 1 line goes to the modem, the other to a DVR. (both lines are only 18 inches.)
Line 2 is the DVR that constantly has tuning issues with certain channels (FamHD, ComCast sometimes etc).
The modem and internet are always on, and rarely have problems.
So, Should I put a Splitter on Line 1 and run a line to the back room DVR, and leave the modem on its own line?
According to the Box Diagnostics the Signals are Good (well fantastic compared to other places I’ve lived), yet certain channels are either untune-able or scrambled.
BTW, what is that Filter?, its been on that line since cox launched digital cable ( whatever it is, it prevents the cable modem from working on that line as well.)
