Can anything Decode with a CableCard without Selecting a channel?
My parents have not gone HD yet, and have no plans to do so any time soon. I gave them my old Series 2 TiVo when I went HD several years ago, and they subsequently bought a lifetime subscription on this TiVo, so they don't want to switch to another DVR. Everything worked fine until their cable company (Charter) switched to a digital signal.
Now they cannot use their cable without a cable box to decode the digital signal. I set up the TiVo to interface with their cable box and change the channel, but it still can only read one channel at a time, which defeats the dual-channel-input feature of the Series 2 TiVo. Even worse, the channel change works about 90% of the time, which means sometimes they try to record a show and end up with a recording of the wrong channel.
When I talked to their cable company, one suggestion they had was to use a Cable Card instead of the cable box. The series 2 TiVo does not accept Cable Cards (that started with series 3), so I have been looking for other devices. But every stand-alone device I can find which accepts a Cable Card comes with its own tuner, and only outputs the selected channel. To make this work with the Series 2 TiVo, I would need a device which outputs an undifferentiated analog signal, so that the TiVo downstream of it can be the tuner, otherwise I would have the same problem as the cable box.
Is there a decoder like I am envisioning, which uses a Cable Card to decode the cable's digital signal to an undifferentiated analog signal, or is there any other possible solution which I have not considered? I've tried searching this site and the internet in general for this type of decoder, but all of the key-words I can think of show up in a lot of web-sites which talk about other things entirely. Any help would be appreciated.
