Alright, let me start off by saying I've searched the forums and not specifically found my answers, so I'm going so far as to post and beg for some advice from knowledgeable folks.
I've got Comcast digital classic and a TiVo series 2 dual-tuner... The wiring back there has become unfortunately the spaghetti bowl, so here's the explanation.
It goes from wall jack to a "genisys 2 -3.5db" splitter (acquired from a comcast tech who was out) which feeds coax into the cable box and also the TiVo. The cable box then feeds the triple-wire connectors back into the TiVo (this gives it the dual-tuner ability) - from the TiVo another set of triple-wires goes to an RF modulator (cuz my TV is older and only has the coax connection on the back) which feeds coax into the TV itself.
This setup works perfectly most times, but lately I'm getting the Comcast "please wait, this channel will be available shortly" message on many channels unless I take the first splitter out of the deal. The TiVo loses its dual tuner ability, but I get channels properly. When this happens the TiVo pops up the annoying "searching for signal on basic cable in" message cuz its expecting two signals and not getting them.
So what I think happening is I'm probably losing signal strength due to the splitter? Or could it bad cables themselves? Why would it have worked so far fairly well, and then fail on me? How does TiVo expect people to hook all this up when Comcasts support immediately tells me to hook directly up to their cable box and not have any splitters in the way?
Is this a common problem? Is there something I can do to fix this?
Thanks in advance!
