Prior to end of April 2012 channels in the range 2-90 were visible to me without going through the Comcast cable box. To receive channels 1 and 100 to 899 I need to use the Comcast cable box.
My configuration is:
1. Main cable line through a splitter.
2. The left splitter cable went directly to my analog (more than 10 years old) TV. I was able to watch channels 2-90 by changing channels on my TV remote.
3. The right splitter cable went into my Comcast cable box.
4. The output of my Comcast cable box plugged into my TiVo cable input.
5. The output of my TiVo (using RCA jacks) plugged into my TV.
6. To watch the output from the Comcast-TiVo configuration I set my TV channel 91 (the AV input). Using this configuration I was able to watch and record all Comcast channels. I could switch Comcast channels using the Comcast remote.
I went away five days the week of Apr 23rd. I left my Comcast/TV setup running on one of the music channels. When I returned from my trip the music channel was no longer working. I had to power off/on my Comcast cable box and reset the TiVo.
Since then my configuration does not let me listen to the music channels for more than a few hours consecutively. After that the Comcast box says the channel is not available.
Couple of questions:
1. The cable splitter I'm using is a Gemini CV60 rated for 5-900MHz. It is old -probably the same age as my TV. Do I need a newer splitter or one that is bi-directional?
2. Do I need to remove the splitter altogether? I could live with this if it's the only option.
So you have pieces of April, but now it's a morning in May.
Does your old analog TV still receive channels 2-90 over the cable?
I can understand why you had to reboot the cable box, but I would think on the TiVo all you needed do was tune it away from channel 3 or 4 (the cable box output) and back again once the cable box was rebooted.
If the cable box is saying the channel isn't available, then either that's a "still" or "slide" the box has in its memory that it uses whenever it encounters lack of signal, or else that message is being sent down the line from the cable company.
Either way, your Television, your TiVo (either tuner) and your splitter have nothing to do with that and no control over it.
How long has your present cable box been part of your setup?
Does it have a brand name on it other than Comcast? Like say, Scientific Atlanta or Motorola?
How about a model number?
While we're at it, how about brand and model on that analog tv as well?
If Comcast is not doing SDV, this is going to take longer and a little more thinking and googling to figure out.
(I had forgotten about the tune to channel 91 trick, we had an RCA that my dad got a deal on because, despite having a numeric keypad for channel entry, it did not have and was not designed for, remote controlled capability.)
