HD Tivo Loses Channels

There is on Cablevision with NDS cards. What provider are you using and what Cablecard do you have?

 

This topic has been and is still being flogged in the cable card threads. Find the thread for the, i.e. "Cox Cable Cards" or "Comcast Cable Cards" etc, and read them for missing channel problems for reasons and possible fixes.

 

As Rick indicates, there are numerous threads about this seperated by provider usually. The gist of it is that there is an issue with SA MCards in some markets where you will lose the vast majority of your channels (when it happens to me, all I have left are 2-22 and SD versions of my HD locals.. everything else is grey/black screen).

I'm not sure of exactly why it's happening but as you indicate, a simple reboot temporarily fixes it. However you need to be aware that this will only work for a period of time before reboots will not fix it anymore. When you get to this point, some folks it seems have had luck with the Cable Co sending hits to the card... but for others like myself, they refused and would only send a truck to swap it out (which puts you back where you started with having to reboot until it doesn't work anymore).
