Re: MANY MiSSING CHANNELS -TIVO with CISCO cablecard and tuning adapter

Exact same problem.  I get almost all channels except ones I pay extra for when I don't use a tuning adapter.   When I put the tuning adapter in the link, I lose all of the "extra" channels plus many more.  I have been through two tuning adapters and used different USB cables.   The problem started about two weeks ago.  I got all channels until then.  Any gurus out there who might help ?  

p.s.  My cable box gets all channels, so it is the tuning adapter and  tech support seems to be at a loss.

:-) The USB cable is connected.

The reason given by TiVo for using the splitter setup is that the MoCA network signal would not pass through the tuning adapter. We had it set up with the splitter for more than three years with no problems. In the course of trying to figure out what was wrong these past few months, we have tried using the tuning adapter pass through and no splitter. It turns out that MoCA works just fine without the splitter, but it has not changed our problem with the channels. One tech even tried a setup with two splitters so that the TiVo input was connected to both the splitter from the wall and a splitter from the tuning adapter out. No change in the number of channels.

We do have their internet but we use our own modem. This is all I can find that seems related:

Re: MANY MiSSING CHANNELS -TIVO with CISCO cablecard and tuning adapter

I know we're getting off topic, but this is interesting. I never considered the implications of following TiVo's instructions that leave you with an open port. I wonder why they would suggest this method? I personally had it hooked up with the splitter at first and everything worked fine (I guess the signals were pretty strong even with the loss) but recently switched to inline just to tidy things up behind the cabinet.

The latter is wrong.

If you have twc internet, copy and paste the modems signal level and error log pages.

 


Either will work assuming the signal strength is enough for the TA to handle. In fact, TiVo themselves recommend the splitter method.

 

Not correct.... all the TA's have an internal 2 way splitter and it's port Must have a 75 ohm load on it. That splitter is a 3.5 dB loss, and in series with an external 3.5 dB loss splitter for the Tivo with probably another 2 or more way splitter for the cable modem and other sets is too much loss. The open port is even worst it can increase the splitters loss by as much as 13 dB

All the TA is , a simple usb output docsis 3 modem... It must see DS in the -6 to + 10 range and US must be below +48 dBmv to work reliably.

Removing the ext 2way andusing the internal splitter  saves 3.5 dB  and the Tvo of course get's the same level

Let me ask a dumb question...Is the TA also connected to the TiVo with a USB cable?

MANY MiSSING CHANNELS -TIVO with CISCO cablecard and tuning adapter

I have been missing channels for months now.  Over a dozen calls into cable card support who tell me that I have to have a technician come onsite.  It takes 3+ hours each time a technician comes onsite and the problem still exists when they leave, telling us we need to call in again.

 

About 6 months ago, I lost my all of my HBO channels, Smithsonian, and many other channels. I believe we are missing over 30 channels now.   We've been through 5 tuning adapters and cablecards.  Technicians have replaced everything that they could.  We have had a new cable buried in the backyard.  We even replaced the Tivo to verify that it was not the issue.  The last technician used a cable to test directly from the box outside to the tuning adapter and we could still see that the problem still exists.  Could this be related to the virtual channel table on the cablecard?  I've asked that multiple  times, but it seems no one on Time Warner/Spectrum side seems to know what that is.

 

All I want is the service that I've been paying for and not receiving.  Is there anyone that can help?

 

TIA
