All Channels Detected As Analog

[patelj27b]

So, for the past few days I have been getting the message on Windows Media Center, on all channels, that "No Signal Found" when trying to tune a channel. After contacting Comcast, I went to the service center and replaced the CableCARD. After much hassle of getting them to pair it, I still get the same issue. After emailing Ceton Support and opening a ticket, it is seen that all the channels are now being labeled as Analog channels, so the card doesn't see them. Does this seem to be a Comcast issue or a Ceton infiniTV card issue?

Thanks!
Jay

What is your area?

I know at one point here TWC split the guide between NTSC and Digital and in set-up you had to select digital rebuild from the drop down for the zip code.... Could Comcast have done some re-alignment that might have caused this?

Also do you subscribe to any premium channels iln HD that would have to be delivered as digital?

It would sound as if this is a comcast issue with the guide and media center. With your area added to the complaint you might see the same problem from others in your area or a solution from others in your area. Remember that each headend can have its own lilne-up and channel offerings.

It should be pretty easy to figure out if the channel map on the CableCARD is wrong. Go to http://192.168.200.1/Services/ChannelMap.html and check the channel table. If you look at the modulation column, all the analog channels should be listed as NTSCM, while all the digital channels should be listed as QAM64 or QAM256. Navigate through all the pages (page navigation is just above the channel table) and check the status. If everything shows up as NTSC, obviously there's something wrong with the CableCARD's channel map. Also, high channel numbers shouldn't be listed as NTSC. If you get above about 125 and it says NTSC, that's wrong.

They all say NTSC. This is a fragment from the XML file:

Yeah, that's definitely wrong. I would contact Comcast and see if they can resend the channel map.

Of course, I guess it's also possible that the InfiniTV could be reading the map wrong. But I don't think that is very likely.

[patelj27b]

I created a ticket with Ceton yesterday, and they said that they would work with Comcast, but I have yet to hear from any of them today. Also, who would I directly contact at Comcast? My interactions with them the last 4 or 5 days lead me to believe if I start to talking to someone over the phone with this issue, they will think I'm talking some foreign language and not understand a word I'm saying.

You can force a channel map download and cableCARD reset by going into the Web Gui for yuor Ceton Device and click on CableCARD and scroll down and then click on "CLEAR CHANNEL MAP"

You'll see the card will be busy with binding and verification then the channel map will be zero, after a few minutes a new map should down load. That at least will clear any issue if there is a bad map in memory in the card.

Hello
It seems I have the exact same problem since 3 days - I am a TWC customer in NYC.
All channels look like to be seen as non HD/non Premium when checking with the Ceton utility software. WMC does not want to show any of the premium channels and is requiring a subscription (that I of course have).
I checked the channel map and everything looks like ok (almost everything in QAM256).
TWC customer service is telling me to post a ticket at Microsoft - they consider everything is fine on their side...

[gbuathier]

Update : I called again and it turns out it was EMMs messages that my card was not getting. He sent some update messages and now eveything is back to normal.

I had cleared the map per the suggestion above quite a few days ago, and now a new map is never downloaded. I talked to Comcast, and they sent a technician over, and they have sent multiple hits to my card, but everything syncs up, but a map is never downloaded.

If you have a Cisco/SA CableCARD, upgrade to our newest beta firmware. In Cisco's latest DNCS (headend controller) release, they introduced an issue that forms channel maps in a way that some devices, such as the InfiniTV, cannot process them. This could cause the issue that you are experiencing. We have included a workaround for this in our latest beta firmware.

After updating the drivers and firmware, the channel mapping downloaded successfully, and I was able to view channels normally. Thank you for your time and prompt replies!
