    You are right. I took the TivoHD downstairs and hooked it up to my 1080p TV and had no problems with fixed 1080i output. I guess I have to live with the 5s delay on switching with the hybrid mode - until I can convince the wife for a new tv!

    I'm no expert but to my eye, the picture quality is significantly better when using native with the panasonic 600u. The switching is a bit annoying though.

    That would mean that your $2000 TV does a better job of scaling and/or de-interlacing than the $300 Tivo. Not totally surprising.

    The real question is does the Tivo do a better job than the Comcast Moto HD DVR box.

    I asked TiVo about the macroblocking issue and they issued this statement:

    Could you define what the macroblocking issue is that people are having?

    I had noticed that after I first hooked up my TivoHD (without cablecards), all the channels (standard analog) looked crappier than I have been used to with my time warner dvr. I hadn't been able to define it, but it's as if the whole screen is made up of little blocks. All channels are watchable, and it's not intermittent (it's constant over the whole screen), plus the issue didn't change once I got cablecards. Doesn't seem to happen on my HD channels, but all others.

    When watching it, I keep getting that "somethings not right" feeling. So I was curious if this is something that other people are seeing, or maybe I should start looking into if I have a weak signal or crappy cables.

    Currently experiencing HDMI/HDCP negotiation issues with my new Philips 47PFL7432D/37 TV. Any time I change to the input, there's a few minutes of signal/no-signal/HDCP error messages, but then it finally works. The error states my TV doesn't support HDCP, but it obviously does. Haven't tried component video yet, but it'd be nice if this issue could be resolved....

    Also running into issues where my analog cable channels stop having audio quite often. FYI, my setup doesn't have cablecards yet (this tuesday install).

    *edit* Happens in both native and forced 1080 modes...

    Have you checked your display settings on your TV? If you are using a different input than before, its likely you haven't set the display settings for that input correctly (since most newer displays have different display settings per input).

    That is NOT what other people are describing. Are the TiVo menus affected or just video? If the menus are affected, it is probably the connection between the TiVo and TV. If it is just the video, I'd suspect the cable connection to the TiVo - bad coax, weak signal, etc.

    Without Cable Cards, you are looking at Analog SD, and your HDTV is probably having problems displaying this with any quality, and could be the source of the Macro-blocking as well. Many HDTVs do a poor job with Analog SD - worse than the plain old analog CRT you replaced.

    With your TWC DVR, you are getting Digital versions of these SD channels, which while not HD, are considerably better picture quality than the Analog version. The problem with TWC is that even with Cable Cards, they don't provide the Digital version of the Analog SD (Digital Simulcast), so those channels won't look any better with the Cable Cards than without.

    I have TWC 83000HDs, as well as a new TiVo HD (with a digital STB sitting beside it for comparison purposes), and you are correct, the Analog SD looks pretty crappy by comparison to the Digital SD version of the same programming. TWC has made it so that you really have to sacrifice to go TiVo...no Digital Simulcast, no VoD, and no SDV channels. They claim they are planning to move all Digital Simulcast channels to SDV, which is why they don't support it on CCs, even though they haven't yet switched.

    This can be proven by simply connecting the cable directly to the TV and tuning in an analog channel to see if it looks the same.

    The idea that high end HDTVs have bad analog tuners is a new one to me. The tuner in the HDTV is probably as good or better than the one in the Tivo. It seems more like this is a tuner problem on the Tivo that will hopefully be fixed in SW.

    I wasn't trying to say that the HDTV tuner is the problem...but the video processing of analog 480i on an HDTV varies a lot from manufacturer to manufacturer, from awful to sorta okay...with the result looking worse to many people than the same source on an analog tv. The issue that was being described was that Analog SD channels look worse on the TiVo than TWCs DVR...I believe the reason for this is that the TWC DVR has digital simulcast, so there are no analog SD channels, only digital SD.

    To update my issues so far: The audio issue that I originally experienced doesn't exist now as described. The only time I have an audio drop is after a reboot with the TV on. I'm going to chalk this up to HDMI handshaking issues.

    On the pixellation issue, the update seems to have done something but I don't think it's completely fixed. Has problems around noon today but none right now for the last hour. Not sure what to make of that. Still need to unhook some coax and stuff and see if that makes a difference.

    The random reboot in the Now Playing must have been a one time thing, I can't reproduce it at all.

    I will say without a doubt - yes. Now I only had the Moto Dvr for 6 weeks and used it sparingly but after the cable card install on the S3- SD as a whole looks much better.

    For those who are seeing pixelation on the menus; I have experienced the same. I just hooked my Tivo HD this evening, and it is in the process of applying the update. Cablecard install in on Saturday. I noticed the pixelation only while repeatedly tasking the system. Specifically, I did a channel scan, and it found over 300 channels; I wanted to see what was on all of those unnamed channels and to see howmany were unencrypted (watchable without cable cards). I went into the channel list and just kept hitting select to tell it to show that channel. After about 30 seconds straight of me just hitting select, the menu started to pixelate (lower right hand corner). I switched cables to a very good set of AR component cables that I have in the basement and started doing the same thing again. Same pixelation cropped up. So in my case at least, I'm attributing the pixelation in the menus to the system being overworked while I was selecting multiple channels (not something that I would consider to be a major problem as long as I don't see it in programming).

    I've had the "pixellation" in the menus and in recorded/live TV both. The visual artifacts look like slightly corrupted MPEG streams, with some macroblocks getting discarded and then the resulting bad image being used in subsequent P/B frames until another I frame comes along to correct the issue. This causes the erroneous portion of the image to shift around a bit for a moment before it goes away.

    Does not appear to be related to cable cards because I saw it before TWC showed up to install the CC for me.

    However if I rewind and play again, it always happens the same. If it was only on what I'm watching I'd assume it was quality issues with the cable signal, but it happens occasionally in the menu too. I'd suspect some form of data corruption, either due to bad hardware (HD, SATA cable, RAM) or overheating components (MPEG decoder, etc). I think my temps are hovering around 35-37c last I checked?

    I'm using HDMI but I never had such problems with the same HDMI cable connected to that clunker DCT6412. It's not like the sort of error you'd get with bad HDMI connection anyways (sparklies etc) since its quite obviously decode/blocking errors.

    I'm hoping either there's a software fix or they find a hardware fix soon and let us either trade in at the store we bought them at or replace/repair for free.

    I woke up this morning and the screen was black, no picture at all. I changed the channel and the picture came up for a second and then locked onto that image (freeze). Changing the channel again would grab the image for a second then freeze again. Everything else worked fine, the unit didn't completely lock up. I noticed that my signal strength as reported in the diagnostics for cable card 2 went from 89 to oscillating between 87 and 95. I rebooted the unit and the picture came back but the signal strength is now 62 for card one and 0 for card two but all the channels work and I'm getting more channel pixellaiton and menu pixellation than I did last night when it was stable.

    Weird - I've had it on for a few minutes now and the signal strength is 93 and stable for tuner 1 (cable card 1) but no signal strength even shows up in the menu for cable card 2 but everything seems fine.

    If you tune to an analog channel then go back to digital, does it clear up?
