    just tell them to go into the 07 screen & hit "Enter", but have your USB cord unplugged when they do. Sometimes that hit will make the TA light go off, & you will then have to hit the power button. Other times it will just make the light go solid & you can then reconnect your USB cord & as long as the TIVo see it you will be good. On Rare occasions that hit will not make the light change & you will have to reboot the TA with the USB disconnected. Wait for the light to go back to solid after it starts blinking though. If for some reason it does not go to solid & goes back to the 8 blink pattern it will be Cable Card Support Desk time & you should ask to be xferred to them. They will have to call the Head End (DNCS) & have them restage the TA.

    You could do what I'm doing and give them back the TA and Cable cards. However when you call them to have digital cable removed from your plan they'll tell you your rate is going up as a result.

    Contstant blinking today on the TA. Rebooted everything.... waited 30 minutes... no go. Rebooted everything again while I called TW. Wouldn't you know it, as soon as I'm connected to a rep, the TA goes solid and the TiVo sees it and starts aquiring channel data.

    Here's the disturbing part. I asked the rep why so many of us are having issues with the TAs. His reply was, "None of us here know of any issues anywhere with the tuning adapters. I've been here over 5 months and I've never had a call about a TA. We aren't aware of any users having issues."

    That got me a little ticked, considering this thread alone is riddled with horror storied of countless people having the SAME EXACT ISSUES with their TAs.

    GD it TW! Get your act together!!!

    /end rant.

    Add Dallas to the list of cites that have SDV as of april 5th they are moving most of our HD to SDV no SD channels are affected at this time:up:.



    Have to give credit to SteveGoTex at broadband reports for uploading the above image.

    We have 5 open analogs right now so they are freeing up 14QAMs on April 5th.

    Nothing new here -- and don't hold your breath expecting it to improve. TWC volunteered to provide TA's just to get the FCC off their back, i.e., so SDV channels could not be viewed as a "reduction in service" to one-way UDCP users (i.e., mostly TiVo's). They have no business incentive to care about how well TiVo's work -- in fact their incentives grind the other way. And TiVo's are about 0.5% of their digital subscriber base, which is why many TWC people don't deal with a TA or CableCARD for months at a time.

    The only thing that might have an impact on TWC is to complain to the FCC and I'm skeptical about that too.

    I see we are neighbors. I've had my TA for nine months now and roughly once a month I get the 8-blinks and have to call TWC. About 50% of the time the rep knows how to fix it right away. And that hasn't changed over nine months.

    What bothers me even more is the pixelation on SDV channels, which SCSIRAID has proved is a TiVo deficiency. I hear they are working on it and there is hope a software update might fix it.

    You keep on repeating that, and it's not true. It may be something that TiVo has to fix, but it has not been proven to be TiVo's fault instead of TW's. There is no proof that TiVo has not followed existing standards in their implementation, or that TW is following the standards. All we have is one TW engineer stating what he thinks is wrong, and that in his opinion TiVo is at fault. A TW employee blaming TiVo and you completely accept it?

    I'm still very puzzled by the fact that this seems to be quite localized problem - many/most folks are not seeing it. That doesn't fit the explanation given. There is still something unexplained here.

    There certainly IS proof that TiVo is not following MPEG standards. The MPEG spec allows programs to added to or removed from a transport stream. When that happens, the PAT changes and its 'version number' increments. If you put an MPEG real time analyzer on the QAM TiVo is tuned to (which we did), every time the PAT version increments, TiVo macroblocks. The Hewlett Packard MPEG analyzer found absolutely nothing non compliant in the transport stream. TiVo appears to have made an assumption (probably to simplify their sw) that the transport stream will always be 'static'. That is absolutely true for linear QAM and OTA television... however... its not true when you introduce SDV into the mix.

    Whether a user see it depends totally on whether the QAM they are watching gets a stream added or removed. This depends on the 'load' on the SDV system and whether folks are 'surfing' or watching statically. If you tune to a 'full' QAM and the others watching that QAM stay put, there will be no macroblocking.

    Be glad you arent seeing it. It would drive you nuts if you were.

    Every month since last October I've had to call TW since my TA goes into the 8 blink brick mode. In December they sent a tech out because they said it was a problem on my end. He couldn't find anything wrong. On March 4th (the same day my bill was cut) it went out again. This time they couldn't get it working so they scheduled a truck roll for the next day. Of course he didn't have a TA with him but the whole scheduled appt. was to replace the TA! The exact same thing happened about a year ago when they were to replace a cable card. I made the the tech stop anyway and he finally got it working again. I don't know how TW functions as a company.

    Yes, I think it's been verified in at least 3 different systems, although it's tough to separate out the normal random attacks of pixelation from what SCSIRAID and others are seeing. It's definitely a very real compatibility problem that needs attention.

    But if the root cause is as simple as SCSIRAID's explanation, it should be seen everywhere just as badly as he sees it and that's not the case. What he describes seems to be a basic failing on the TiVo's part that should affect every SDV system out there equally. But there are a whole lot of SDV'd TiVos, and the reports seem to be only from a few locations. Perhaps those locations are the only ones with a heavily loaded SDV system so that they need to add and remove streams from a QAM, but that seems unlikely. I'm not convinced we have the whole story yet.

    I have no "normal random attacks of pixelation" on my non-SDV channels -- where pixelation is extremely rare.

    There are two factors that could lead to a mistaken impression that the "SCSIRAID" effect is localized to only a few TWC locations:

    1. SCSIRAID's investigations, which are somewhat unique, have been reported mainly in the TWC Carolinas thread, where it is not likely to be noticed by Cox, Charter, ComCast, etc. subscribers, and less likely to be noticed by TWC subscribers in other regions. Seeing his posts prompts people having the same problem to post, and vice-versa.

    2. You may not be noticing SDV pixelation posts as much as some of us who have the problem and thus tend to search out such posts. For example, **this thread**, which includes complaints from other cable systems and places.

    We may never know the "whole story". TiVo may know it but probably wouldn't tell us if they did. SCSIRAID has at least given us a major piece of the story.

    I'm not trying to diminish the importance of SCSIRAID's investigation. It's excellent work and indicates a problem for both TiVo and TW to look into.

    But there are many potential causes of pixelation, and even of pixelation on just SDV channels, and even of pixelation with 0 RSS errors (which I see often, with no SDV). A good number of the reports in the thread you cite (which I follow) and other threads are not the same problem. People reporting pixelation starting and intermittently continuing for 45 minutes are probably not the same problem, as I understand the issue. People reporting constant pixelation on only one channel are almost certainly not the same problem. Some of the reports have symptoms matching much better, and are potentially the same issue. Nyijedi is almost certainly the same problem, though Time-Warner in the NYC area has lots of other issues also!

    Given that perhaps 20% of cable users have SDV, and therefore I assume 20% of the members here, we are not getting the number of complaints I would expect from a problem that SCSIRAID describes as "Be glad you arent seeing it. It would drive you nuts if you were." I also am not seeing reports of the timing correlation that SCSIRAID observes and is good evidence of the conjecture that stream addition is causing his problems. Unless we understand why we aren't getting those reports, I'm reluctant to conclude that SCSIRAID's explanation (which would affect TiVos on every SDV system out there) is the complete answer.

    That's good --- I was confused by your earlier response to my post where you seemed to toss off his work with: "A TW employee blaming TiVo and you completely accept it?" ;)

    What would you expect TWC to "look into" if the mpeg2 analyzer says their signal meets standards?. :confused:

    Crispy asks some reasonable questions... It surely seems that many more folks should be seeing this. The only explanations that I can offer are 1) People are not recognizing that the issue is limited to SDV or that the SDV breakups are somehow 'different' from 'run of the mill' random pixelations that are seen on both TiVo and Cisco equipment, 2) They arent seeing them because the usage habits of folks in their service groups arent causing TS updates 3) Their systems simply dont have much interesting stuff on SDV. Here in the Carolina's, virtually ALL of the non-premium HD content is SDV. That pretty much assures good probability of seeing the issue if you are watching HD. The issue has been reported in not just TWC but also Cablevision areas. It has been reported on both Cisco and BigBand equipment. I would expect to hear more complaints about it and I cant explain why that isnt happening. However, there is not a grain of doubt in my mind as to what the issue is and where the problem lies.

    I did discuss with TWC whether it would be possible to implement an SDV system with preallocated programs which would yield a static PAT. This wouldnt excite the issue... but TWC Engineering stated that it didnt meet MPEG specs and that wasnt the way Cisco or BigBand worked. From my reading of the spec, I agree with them as if the PAT didnt change version numbers, the receiver of a stream would not be aware of any content changes. It probably wouldnt matter to a TiVo like implementation but the spec has to cover ALL usages. Even if such a system DID exist, it doesnt change the fact that the current TiVo implementation cannot handle an MPEG standard transport stream and that TiVo needs to get in line with the MPEG standard.

    that wont work as the SDV protocol calls for the x-xxxx channel designation this is not a TWC decision it is industry standard whether you use Motorola, Cisco, or bigband SDV servers they all do this it is probrably a SCTE standard.

    Also there has not been a problem with motorola tuning adapter pixelating on SDV channels using bigband SDV servers. so this is a cisco problem with the Conditional Access and tuning adapter.

    Did you know that the color bars test pattern is a SCTE standard so they have standards due to euipment compatibility requirements.

    Twc Dallas gets to try out SDV starting on april 5th only the HD expanded channels are going except for the popular HBO HD,SHO, and HDPPV now has replays going so they dont want it to kick you off of your program and you loose your money due to system issues such as timeout.

    They have 30 and 40 dollar events on HDPPV everyday even if it is replays and the adult programs late at night.

    The 'channel number' is not what I suggested be static. The suggestion was that the 'program number' in the mpeg stream be static.... and as I said in my post, I agree that its not in compliance with the standard. I believe it 'would' work for TiVo but its not going to get the chance because its non standard.

    The tuning adapter in this case has nothing to do with the pixelation. The issue is TiVo dumping the CP encrypton nexus when it sees the PAT version increase.

    TWC Austin is a Cisco plant using BigBand SDV and it shows the problem as reported by several folks there....

    you total ignored that I said the motorola tuning adapter using the bigband solution does not have any pixelation with SDV channels, because TWC maines motorola areas deployed the bigband solution and the MTR700 had no problems and no pixelation on SDV channels.

    I already knew that austin uses bigband with SA boxes so the problems is not the tivo it is cisco.

    I'm a Time Warner costumer in Cary, NC and I have this macroblock/pixelisation problem big time with SDV channels. At this point, would it make a difference if I get in touch with TiVo to complain about this?

    They already know. Someone posted that they called TiVo and was told that a fix was in progress. I have no conformation of that though. Never hurts to add your voice though.

    Im in Apex so Im in the same boat.
