    OK... Are you only seeing the macroblocking on SDV channels? Are your signal levels good? Are any channels worse than others?

    Honestly? I don't know if I'd call it macroblocking so much as the whole pallet shifts with pixelation along with freezes and audio drop outs. I think it's pretty much the SDV channels but I'd need to see the complete list again. Frankly I haven't had much time to play with it and check signal levels carefully. I did buy some PADs to see about playing with the signal level but I haven't had a chance to play with them either.

    Too bad working for one of the three companies trying to figure this out (albeit the "wrong part") doesn't get you any extra help... :p

    HAHA... I know what u mean... With three companies in the mix of this issue it is a challenge. TWC Raleigh has to work thru Cisco to get to TiVo. TWC Raleigh has been great. They have got some really good people. They agree that this is a problem and have been working on it but no smoking gun yet. They have determined that it is NOT an RF issue and that is a huge step in itself. We tried moving signal level up and down and it made no difference. TWC brought a QAM analyzer out and the constellation diagrams were perfect. They brought an MPEG analyzer out and all was fine. There are a few more experiments planned and I believe the next one or two will yield the smoking gun. :)

    Just to restate... the issue is pixelation/macroblocking on SDV channels only. Linears are fine (Linears exhibit some random pixelation once in a while but nothing significant - most likely from transient signal problems or the content provider). The worst I have seen is on USA, Speed and Bravo. Ive seen it on pretty much all the SDV channels. The SA8300 does NOT display the problem... only TiVo.

    It's pretty bad on USA (I know a lot of Royal Pains and Psyche episodes have had issues). Is SciFI (er... SyFy) SDV? I've seen a few issues with episodes of Eureka too. Of course we lag so far behind it's more archeological data than anything. I know ScienceHD has a lot of issues (and is one of the few we watch live frequently).

    All of those are SDV.

    Just a reminder: You can determine whether a channel is SDV using the TiVo menus as described in ***this post*** and the post it links to.

    I'm in the Burlington, NC area and got TWC to install a TA a few months ago. We never got it working so I disconnected it to wait until TWC could negotiate the learning curve on the new technology. I've reconnected everything, run the TIVO Guided Setup, everything looks reasonable in the TA diagnostics, although I don't know what's critical.

    After doing this I'm getting the same behavior, the SDV channels don't come up, I get nothing but a black screen. I've got a TWC tech coming in tomorrow, and I know from past experience it would help to have a game plan.

    Can anyone suggest where to go from here?

    Have you tried the documented workaround (re-tuning) for this behavior?

    http://support.tivo.com/app/answers/detail/a_id/148/kw/sdv/c/123/p/88%2C90/r_id/100041/sno/3

    Also, go to the DVR Diagnostics page and note the following info for the tuner that is assigned to the channel you just tried to tune:

    Signal Lock
    Program Lock
    PID numbers (3 of them)
    Frequency

    I get this same behavior, but only occasionally. In my case the Program Lock will say "No", which is the problem in my case. And the workaround does work for me. Very rarely, I have to re-tune 2 or 3 times before it succeeds.

    I've tried the workaround with no success. When I run the DVR diagnostics it hangs and displays please wait.

    Are you doing:

    Messages & Settings --> Account & System Information --> DVR Diagnostics ?

    Ok, in DVR diagnostics I'm getting a screen with null or zero values

    Current tuning status is "not tuned: wrong card state"

    That typically means that you have attempted to tune an SDV channel but dont have a TA.

    Look at the very bottom of DVR diags... the last three lines... what do they say?

    I had a tech come out today and we did simul recordings on USAHD and TLCHD.
    When either channel Macro'd on the TiVo, it did not appear on the Sci Atl Box.
    He changed out the Cisco TA (my 4th one I might add) and now they are back to blaming my S3 TiVo box.
    Don't these guys talk to each other or is blaming TiVo again all they have left?
    I called TiVo who blamed Cisco.
    Round and Round we go, I've had enough of all the crap.
    I told the tech it's only on SDV Channels and he couldn't tell me why when I asked.
    The problems we saw were mainly compression related (partial rather than full on Macroblocking).

    Welcome to the club...... :D It would probably be a good idea for TWC to at least inform their CSR's and Tech that a problem exists and they are working on it. They are wasting their money sending techs and replacing TA's to try and fix this.

    AFAIC, until the issue is fixed, I'll just get the programs affected by this by other means (Hint, hint!) and load up to my AppleTV. At least that's watchable. :D
    I think all Tivo owners affected by the "reduced service" should ask for a discount each month this goes on.

    Discount from who? TWC or TiVo? At this point nobody can say who is 'at fault'. :eek: Perfect conditions for finger pointing. I must say I have seen much more direct action on this from TWC than from TiVo.

    Sorry, TWC since they (along with the rest of the Cable Industry) forced SDV on everyone.
    If they got rid of all the Shopping Channels, Political Channels, etc., I'm pretty sure they'd have the bandwidth for many of the Channels they switched to SDV.
    But that's just my frustrated opinion. :(

    Understand... I'm frustrated too. However, if the problem turns out to be what they currently think it is... SDV isnt the 'root cause'. The issue could just as well be on the linears too if the compressors were set up the same. That would suck royally.... :)
