I have noticed some videos on YouTube creep along and some are fast.
post #7292 of 9937
Well, what's wierd is this video is perfect at work - at home, it is unwatchable! I've heard that Comcast's DNS routing is hosed up - that could be some of it.

Have you tried OpenDNS? I use it all the time instead of Comcast's DNS.
Also, Google now has a public DNS server.

OK - swapped my modem out Saturday (2nd time in 2 months), and also pointed my router to Google DNS, and now everything is hunky dory! Speedtest.net shows 20mb download speeds (ran several times, late at night as well as in the middle of the day Sunday), whereas before it showed maybe 5mb (now, I don't know how accurate this is, I didn't go to DSLReports to run their tests - seems kinda high, but it works!)

Anyway, after swapping my modem, all I got when I tried to go to the internet was a Comcast screen about initializing the my Internet service! Called, and they said they saw the problem, but that the system to fix it was down, and he would call me back when it was up (yeah, right!). Waited 2 hrs., no call back (doh!) so called again, this time the guy said I had to bypass my router and connect my computer directly to the internet - I told him I'd call back later! Called right back, got someone else and they were able to do what needed doing to get my modem initialized. What great customer service!

How would a DNS server speed up download speeds? I did change to Google DNS, not sure if that made a difference, or it was just a bad modem again.

Network friend of mine at work told me if you system is off for a while and you bring it back up, you will probably get assigned to a new virtual lan on Comcast's network, maybe one that is not as congested. Anyway, after this weekend I am not only able to stream again, but I can bring up my home webmail server from work and actually download from my FTP server at home - something I could not do for the past couple of months.

Dwight Silverman has an article up that references an unnamed Comcast spokesperson as stating the Houston market will see Docsis 3.0 rollout in the first quarter in 2010.

I know, don't hold your breath, but there it is.

I have no experience with Comcast in Houston and my specific questions are:

(1) Would a subscriber to Basic and Expanded Basic, upon buying their first HDTV, be able to receive digital HDTV signals for the local Houston stations by plugging their cable directly into their HDTV?

(2) If so, is intermittent HDTV service on those local channels readily correctable?

Here is the longer narrative on what's up, which you can skip if you're pressed for time. I don't have Comcast and never have. I have a neighbor across the street. She's an 88 year old widow with no local family. Surprisingly feisty and independent. My wife and I try to visit and help her out with stuff she can't do alone. (That turns out to be most things.) Her name is Juliette.

Juliette is currently subscribed to Comcast Basic and Expanded Basic for about $55 a month. Until this week, her TV was a tiny 20 year old box. It is her primary daily companion. She wanted a new one. I volunteered to help. Studied pricing for months and finally grabbed her a 32" HDTV this week. I installed it, hit autoprogram, and everything loaded.

I was psyched to see that the local Houston channels (2, 8, 11, 13, 26) loaded not only in standard definition, but also in high def. (For example, KHOU Channel 11 appeared at channel position 11, but the digital versions also appeared in HD 11.1, 11.2 and 11.3)

So her 88 year old jaw hit the floor when she saw, for the first time, her beautiful new HD images. Flabbergasted and delighted. A rewarding moment for me too. Big win.

So now the problem. Over the next few days, the digital versions of most of the locals, including the HD options for 2, 8 and 13, come and go randomly. When the signal disappears, she gets a No Signal message at those channels. I stop by and confirm this is not caused by operator error. Reprogramming does not provide a reliable fix. (If the signal isn't present at the time of reprogramming, this exercise merely deletes the options for the currently missing digital signals from her channel line up. When I reprogram for her at a future time, if those signals are available again, the channels reload into the menu and voila she has them all.) That is where we are today, with all of her local HD and subchannels available, but I have to assume it is only a matter of time before one or more wink out on her again, to her elderly frustration.

I called Comcast. The tech rep said she had never heard of anybody getting the digital locals (like 11.1, 11.2 and 11.3) over their wire. She said Comcast does not provide them, and therefore, Comcast could do nothing to return them. As the tech rep was talking, we were watching ABC's programming in HD on 13.1 on their wire. The tech rep said the only option was to come get a digital converter box, but even then, the tech rep said, J would no longer receive 11.1, 11.2 and 11.3 for KHOU (for example), but merely a single CBS feed at channel position 11.

Because part of what J was so excited about was having the multiple local subchannels available, that's really not a perfect solution for her. Plus, the confusion of an additional remote may be more than the 88 year old widow can manage. She never had a converter box on her old set and liked it that way.

One additional fact. She's had cable for 20 years and has never had Comcast out to her house. She is getting a truly terrible signal on many channels that is virtually unwatchable. I don't know if that quality-of-signal issue in and of itself might be causing her to have the intermittent HDTV service on her locals.

Regrets for the length of this post, but I'm trying to help an elderly neighbor, and somebody with some Comcast savvy can enable me to render the best solution and advice for her. I think the tech rep was an idiot, but will appreciate your input on that. Many thanks in advance for your help.

mogrub,

First of all, Bless You, for helping her out like that. The real reward for doing stuff like that is yet to come, but, you may have to wait quite a while for that.

Secondly, I'm really confused by the process you've described there !

I may not be "seeing" apples to apples here, since I've got Comcast Dig Preferred, via their Scientific Atlanta 3250HD Box.
I also have a separate line for my OTA, which I access via the sources in my HDTV.

Customarily...
One can not receive HD, with a direct connection of the Comcast Cable into the "F" connector of their TV, even if it's an HDTV. Those lower channels (2-99) are still NTSC/Analog. Even with the Basic Service, one must have one of their Boxes, to receive HD, and even with Basic, they provide a "few" HD channels.

The inconsistency is what's confusing. I've tuned in Digital on a Comcast direct connection, but, I was using a Samsung H260F D/A Tuner. That gives you the 75.1 to 135.### channels, and you receive what's not scrambled. Very few by the way.

Does her new TV have all three tuners ? NTSC/Analog, ATSC/Digital and QAM ?

I think I can say this for sure...
IF you want her to see reliable HD via Comcast, you're going to have to get her to rent one of their Boxes.
With that, the HD that Comcast provides, is VASTLY inferior to what she could receive, IF she were to get an OTA Antenna. Depending on where she lives, probably a Set Top Indoor may work.
I guarantee you, when she sees OTA HD, she'll be sorry she's paying for what Comcast delivers !

I have my OTA Antenna Coax, connected into the Antenna "F" connector, and am using A/V (component) for the CBox.
I'm not sure at this point, if I've actually answered any of your questions !

But I have a couple...
Does she now have an OTA Antena outide or inside ?
Is she renting one of the Comcast Boxs ?

Have a good Day !
S.W.

The Comcast Tech Rep was wrong when the Rep said that Comcast does not provide digital subchannels (like 11.1 etc.). For example channel 310 is 11NOW and channel 314 is Live Well HD.

I think the reason the local digital channels go away is because they are transmitted using QAM and Comcast changes the QAM frequency often. When the QAM frequencies are changed a rescan is required to get the new frequencies. Using a set-top box would eliminate having to rescan and she may be able to see more digital channels. She could get a Universal Remote that controls more than one device. Comcast provides a Univerisal Remote with its DVR set-top box, but I don't know what kind of remote the other set-top boxes use.

The cables probably need to be upgraded for digital signals.

Very helpful, thanks RussB. Two follow up issues.

Currently, J's local digital subchannels are appearing at their literal positions -- that is, 11 (a non HD version of KHOU) is followed immediately by 11.1 (an HD display of the current KHOU programming) and then by 11.2 and 11.3, and then 12, and so on. Your post referencing those KHOU subchannels in the 300 range makes me wonder, is it is surprise to you with your Comcast knowledge to hear that J gets them at the positions she gets them, and does that suggest any other observations to you?

Second, if QAM frequency changes are the cause of her intermittent loss of those digital locals, is the fact that (a) rescans often don't relocate those channels for a day or two and (b) some of the digital locals never disappear consistent with the QAM shift theory?

I hear you on the universal remote. Good idea and it might work. (I sure do love my Harmony.) But I can't tell you how much a solution that doesn't introduce a new box and (another) new remote is preferable here, given the age and techno-reluctance of the user.

Comcast told me that with what she was paying, she was already entitled to digital service. I don't know if there is anything required to enable them to deliver her those enhanced signals, other than the necessity of having me pick her up the box. Do they do anything else to enable digital signal delivery, particularly in the context of her home having not seen a Comcast (or predecessor) service call in two decades?

My fear is, I don't want to encourage her (and it will take that) to have a service call, only to have the on-site tech do something that diminishes her chance at having a no-box service that delivers the digital sub-channels at the positions they currently (if only intermittently) reside at. She likes it that way, so getting to that end result is sort of my driver.

And if she is going to have to learn an entire new box / remote / channel sequence, she can probably go all digital more cheaply via a sat provider. Plus, if she has to have a box, that way her box would be a DVR.

Any thoughts appreciated. Many thanks to all.

Thanks SW. One surprise here is that I merely plugged the existing line into the new TV and it rendered HD locals at 2.1, 8.1, 11.1, and 13.1 for sure. (Memory fails me on what displayed for the remaining locals.)

Don't recall the range of built in turners on her new set, will have to check and advise.

No, there is no antenna of any kind connected to anything, just the vintage cable line.

Agreed on the over the air quality. I've discussed that with J. Great cost savings for her too. But she has must see TV on a bunch of the cable channels that render an antenna solution (at least as a stand alone) not to her liking. She may not be a technophile, but she is not lacking on either opinions or preferences!

Many thanks.

I am not surprised that she gets 11.1 at 11.1 and 11.2 at 11.2 and so on. I think her TV maps the QAM channels to these positions. There is information in the QAM signal that describes this.

I don't know the answer to these two questions.

When I first got Premiums OnDemand service many years ago, the cable company had to upgrade the cable wiring in and outside of my house. This was when the cable company was Time Warner before Comcast took over. Later on, the cable company installed an amplifier that corrected some problems with the picture quality and OnDemand service not working consistently.

I don't know of a solution that doesn't require a set-top box. I agree that getting a set-top box will require her using new channel numbers and will be a pain for her to learn. I think you should call Comcast again and see if you get a different answer than the one you got from the first Comcast Rep that you talked to.

I don't think getting the cable wiring upgraded or getting an amplifier installed if needed will diminish her chance of not needing a set-top box.

She can get a DVR set-top box from Comcast if she wants one.

I haven't noticed any problems with any part of my internet connection. Do you think comcast's "speedboost" could have something to do with the low download QOS?

Plus, the confusion of an additional remote may be more than the 88 year old widow can manage. She never had a converter box on her old set and liked it that way.

One additional fact. She's had cable for 20 years and has never had Comcast out to her house. She is getting a truly terrible signal on many channels that is virtually unwatchable. I don't know if that quality-of-signal issue in and of itself might be causing her to have the intermittent HDTV service on her locals.

Regrets for the length of this post, but I'm trying to help an elderly neighbor, and somebody with some Comcast savvy can enable me to render the best solution and advice for her. I think the tech rep was an idiot, but will appreciate your input on that. Many thanks in advance for your help.

There is another possibility. The HDTV may be picking up the local channels over the air. The Comcast cable wire could be acting like an antenna. This could be the reason why she is getting a terrible signal on some channels. You can remove the Comcast cable wire and try using rabbit ears and see what channels you get.

mogrub,

Comcast most certainly do broadcast the local SD and HD channels over QAM. The frequency changes are not that often, so I doubt that's what's causing your problems.

A little while back Comcast started sending TSIP data for the locals which is why the channel numbers are being correctly set for you. They don't send the data for the non-locals, so those channels will appear with seemingly random IDs.

You can view a list of the available channels here:

I would suggest that the problem with Juliette's TV are either signal related, or a problem with the TV itself. I'd lean towards the signal. If you have a different device (ie. another digital TV or PC with an HD tuner) that you can plug in to the cable, you can rule out the TV being the problem.

Cheers
Bob

Is his provider Comcast? I notice his download speed (3926880 bps) is much lower than yours and mine.

Still pictures look ok, but movement brings problems. It almost looks like an SD signal. Either that or they aren't broadcasting a 720p signal and comcast is converting it(maybe several times)


Fri While watching the Duke/UCONN game, I did not detect any video problems, but when the NBA Heat-Wizards game followed I did get the above video problem. Could it be that the fault may be with ESPN and not Comcast.

I have been having big problems with ESPNHD & ESPNHD2. Comcast HAS to get this issue resolved.

mogrub,

I think it's apparent that Ms. J doesn't have a QAM tuner in the set.
And, that the existing Tuner is somehow picking up, and displaying the Local channels in the Digital format (2.1-8.1) etc.

Now a couple things...
As far as I know, when someone signs up for Comcast, regardless of which level, they get a Box.
Not a DVR, but at least the standard tuner and remote for the Comcast Cable service.

What happened to her Box ?

IF she wants to access the full service, with consistent channel numbers, with access to the (few) HD channels, having a Box has got to happen.

It should be plugged into one of the A/V inputs (HDMI/Component/S-Video/whatever) leaving the "F" Antenna connector of the TV, unused.
The incoming cable would be connected to the Comcast Box "F" connector.

Now, if you say that there is no box there, Comcast is going to wonder what happened to it, and if you require another, they probably are going to want to charge you (full price) for the replacement. ie: you lost it, you pay for it !

Your only other option is, if you can convince Comcast that a Box was never delivered with the original installation. (good luck on that one)

So, two good things will come from the Box...
The Channels will be consistent, and she will be able to access the ones she was getting, plus more channels than she could with the TV Tuner. and...
The standard Digital Tuner in the TV, will be free for some sort of Antenna Indoor/Outdoor where she will be able to have a backup, when the Cable Service drops out (and believe me, IT WILL).

Have a good Day !
S.W.

mogrub,

I'm getting WGN America via unencrypted QAM on channel 80.1. See if you have anything up around that range.

Cheers

Bob,

If you don't mind me asking...
But how many QAM channels do you get.
The ones where there's actually a reasonable picture with sound ?

mogrub,
I need to explain something I said...
A long time ago, Time Warner did installs, and included a box on the Contract, though it wasn't specifically identified.

That's what I'm talking about on my last post, look at her Bill, and see if there's anything that relates to her supposing to have a box.

Have a good Day !
S.W.

mogrub,

I would double check and make sure the TV has a QAM tuner, it sounds like it does but just check. It is illegal for Comcast not to provide all local channels in HD via unencrypted QAM, without a box. While Comcast will more than likely deny it, the FCC enforces it to be unencrypted.

A few years ago many of us never got a box because literally every channel was unencrypted. Every channel from ESPN, HBO, PPV to any movie your neighbor next ordered, until CC encrypted them to force us to get a box. I havent checked on the QAM channels in a while but when I did last they did have them as 11.1, 12.1 etc.

Im guessing her house has some old cable and probably need to be upgraded to RG-6. CC should do a full rewire for free if needed, but might want her to do a cable protection for $1 a month.
