    Update from me as well...

    Purchased the attenuators that were recommended earlier, added a 6db,3db,10db and got my SNR down to 31db-33db levels..

    Pixelation has gone away so far, but there is still quite a few of uncorrected and correct errors in the diagnostics... I have gone ahead and ordered another TivoHD replacement anyway, I've had other issues with the box so it can't hurt to just swap out the unit, will update once I get the new unit tomorrow.

    Second update. Dave from Tivo called in response to my call to corporate and he had me go through all sorts of diagnostics on the "bad" channels. You can actually see signal loss every few minutes with one cable card worse than the other. According to Dave this is a known problem with NDS cards. We repeated the diagnostics with the second box which has no pixilation problem and sure enough the card diagnostics showed a steady signal for the same channels.

    The second TIVO is much further away from the source coming into the house and Dave thought that it is getting a slightly weaker signal which sometimes helps. He recommended getting an attenuator to weaken the signal to my first box. He suggested that I swap boxes but my daughter is paranoid that the result will ruin her picture.

    Tivo, according to Dave, is working with Cablevision and NDS on the card problem and hope to have a solution in the near future. I will report back on the results with the attenuators.

    Replaced both units from Tivo. Both working fine. Bad Tuner on Tivo HD, and I think I had a bad hard drive on the Series 3.

    I think I've finally cleared up my pixelation, after 2 months of trying. What seems to have done the trick was Cox putting a signal equalizer/tilt compensator on the line (this levels out the signal on all frequencies). Then I replaced one last piece of older (though RG-6) coax, and finally I attenuated down -3db. My problem channel still shows higher-than-normal corrected errors if I leave it on for a number of hours, but no uncorrected errors. My feeling is there is some problem with the signal -- maybe higher than normal bit errors or something -- and the imperfect cabling, too hot a signal, too much signal from lower-frequency channels, plus the mere existence of cable cards was enough to turn this into pixelation on that channel. There's probably still a problem on the channel, but it's not enough to cause significant pixelation anymore.

    Too bad I'm still having other serious problems with the Tivo, like inexplicably missing channels...

    I too am having pixelation troubles with Verizon FIOS. I have a question I have not seen anybody touch on. I have two TiVos. One Series 3, one HD. The Series 3 works perfect, hardly ever seen a corrected packet and never a an uncorrected one. While the HD has all kinds of issues and many channels are only useable only after 24db of attenuatuation. Believe me all things are equal between the units from a signal standpoint as I have swapped cable cards / cables / splitters everyway possible and the results are the same.

    The one thing that I find different between the two is the Series 3 shows Channel Bits: 30750 in the diagnostics screen, while the HD unit shows 30746. What does this number mean? Could this be the cause of my problems?

    I get the same "30750" on my tivoHD. All we can do is speculate, don't expect any Tivo people who read this board to respond with the truth.

    It is MO that they made an executive decision to deny the problem is theirs. It is probably a hardware deficiency that cannot be corrected by the software. You will probably see the next generation (s4?) have different tuner circuitry or a new rev of the present s3 with the circuitry fixed. Either way they will never admit the error. If they did they would have to replace every S3 and HD out there, which they are too cheap to do, or more realistically will tip them into chap. 11.

    Are you saying that you have 30750 and you have problems? My unit that shows that number has ZERO problems.

    Ok then, maybe we are onto something here. What channel bits do others have that are having the problem? For that matter how about any of you that are not having problems, what number do you show?

    So far this is the count

    30746 - two units WITH problems
    30750 - one unit and NO problems

    Regarding grey screen on TiVo HD units, a bunch of us from the TiVo.com forum have been discussing this and TiVo, rightly so, pulled the posts.

    TiVo has been sent the draft of the press release "TiVo HD Owners Consider Class-Action For Poor Product Engineering and Support: Group To Investigate Having A Judge Certify A Class For Lawsuit"

    TiVo has not responded to the draft, but please read the release and if interested, send an email if intereted in joning the class, should a lawsit be filed and a class certified.

    Just as an FYI, the Forum is actually tivocommunity.com. TiVo, Inc. has nothing to do with this forum. It is operated by Capable Networks, an independant organization. As such TiVo, Inc. does not moderate this forum, does not have the ability to modify or remove posts, threads, etc.

    EDIT: It just occurred to me that TiVo, Inc. has their own forum. I forget that it's even there it's so poor and probably why they have a link to this one. I've no idea why they waste their time with it. I'm sure they are fully capable of removing posts though...although based on what I've seen I suspect TiVo Inc. folks visit this forum more often than they do their own and probably don't pay much if any attention to the few posts that it gets.

    Let's make some more attorneys rich. They are the only ones that benefit from Class Action. The last time I was involved, after about 5 years, I received a check for $1.74 as part of the class. Attorneys got the bulk of the $50M settlement.

    +1 :up:

    Plus I'd have a difficult time at best trying to demonstrate how I was "harmed" by a product like TiVo that was clearly malfunctioning and could easily be replaced under warranty. "Oh, those support calls, and the UPS shipping and deliveries...they've caused me so much mental pain and physical suffering!" :rolleyes:

    Now if TiVo's airbag failed to deploy during an episode of Cop Rock or something...then I'd be inclined to get a bit litigious! ;)

    Okay, back to our regularly scheduled programming already in progress (read: back OT).

    Tualatin,...
    Sometimes it helps to smack a company on the side of the head with a "clue by four". That's what a class action lawsuit does. The lawyers make a lot of money; sometimes the "victims" lives are improved in some small way.

    The attorneys are not always the only ones to benefit.

    My wife calls me a TiVo windbag because I always say how much I like it.

    That said I feel TiVo support could stand some help. They just don't seem to care.

    Agreed, I've had both good and mediocre service from TiVo CSR's over the years. My last round (billing) was especially frustrating...I was given total misinformation. However on other occasions it's been very pleasant and satisfactory. I haven't met a company yet that budgeted enough on training/paying their support people...hence there's often a revolving door.

    I also think a lot has to do with both party's attitude going in. After having read some of the rants (some legit and others from another planet :eek: :rolleyes:) here I can imagine how those folks came across with TiVo's CSR's. Couldn't pay me enough to deal with it!

    However by comparison to other companies, TiVo support has been above average in my experience(s). There's always room for improvement though and YMMV.

    I have one of the early Series3's that included a cup holder. I'm very careful about that sort of thing. :p
