I wanted to post this and see if anyone else is having a similar issue. Last Sunday, for no reason, during the UFC special, the video on my Tivo just froze. When I switched to the second tuner to check the channel, no matter what channel I go to, I get "Searching for signal on this cable channel." Well, I called TWC and the guy at the cable card help desk said he couldnt ping my tuning adapter, it must be bad and I should go swap it out. Next day, I run out at lunch and swap the tuning adapter. That night I hook the new one up,same thing. Call TWC back, they reset the tuning adapter and my video comes up and Im all happy. Next day, back to "Searching for cable signal on this channel." So.. I called TWC again and they tell me it has to be my signal and the signal level is too low to work with the tuning adapter. So this morning a tech comes up and yea, my signal is low but its not THAT low. But Im back to not being able to get any video with the tuning adapter in the loop. HOWEVER.. once you unplug the USB cable from the TA,even with the TA in the loop, you get video. That kind of shoots down the whole "running it through the TA degrades the signal too far" aspect of things since my Tivo can tune it fine and its on the other side of the TA. Im wondering if a recent firmware update from either TWC or Tivo is causing this issue.With the TA out or disconnected, I can get all the non SDV channels. As soon as I put that TA back in the loop, I cant even get a channel guide. Instead I end up with "Tivo can find no channels you are authorized for." Has anyone else seen anything like this?
