    I am a technician for my local cable company and I have both a regular Tivo and a HDDVR from my company. I can say this is not limited to just Tivo or DirectTV. I think it has to do with the HDMI port and the way FOX broadcasts their content. It doesn't tile for me but the sound does intermittantly go out on all the shows I watch: 24, Family Guy, American Dad, War at Home, etc. The sound is fine on all the other HD channels and also on my seperate HD box using component then into Tivo.

    Count me in as one of the people who gets horrible DFW 4-1 pixelation. Maybe we should we start a letter-writing campaign to every advertiser on the popular shows like 24.

    Last night I watched Tuesday's episode of House recorded off KDFW 4-1, and I didn't notice any breakup like I saw in abundance last week.

    And that is exactly what I am trying to help you with. I didn't mean to sound flip about it.

    The probablilities of A/B/C/D from my POV, tho, are this:

    A. Virtually nil. A network problem would be fairly wide-spread, and would also be hopefully fixed rather quickly. There are minor differences between how various timezones get the FOX feed, but those are VERY minor, and even a problem localized to a particular feed would not exist longer than a day or so.

    B. Next to nil. FOX affils are virtually locked out of the signal chain. Even the "local" bug you see identifying the local station comes, ironically enough, from the network feed directly. There could be a local splicer problem, but no station would allow that to drag on as a problem for more than a few days at the worst. One of the great things about digital broadcasting is that the integrity of the signal is locked away from most potential problems from the point it is encoded to the point it is decoded in your STB, assuming you can receive the signal properly, and this eliminates a whole host of potential transmission problems that DT is completely invulnerable to.

    C. Not likely. If just one station does this, how could your Tivo pick only then to exhibit a software or hardware problem? Not impossible, but not likely. OTA HD is not identical, but the signals are closely standardized, meaning if you can get one, you can very likely get them all, all else (reception issues) being equal. If sat programs also show this problem, suspect a HDD. Otherwise, I wouldn't suspect the Tivo, especially if it isn't uniform over the other OTA channels.

    D. Actually less likely than C. Pixellation/audio dropouts are almost always due to disruptions at some point before decoding takes place.

    So if we assess A/B/C/D levels of probability of 1%, 2%, 8%, and 3% respectively, that means that there is some other factor we have not considered that has a probability of 86%, which is about what one would expect if one looked at reception. At that level of probability, it seems sensible to look there first rather than picking A/B/C/D as the culprit.

    But it still could be a FOX or affil issue. Some early splicer problems showed up only on certain tuners, while other tuners sailed right through. But again, that was fixed in a matter of hours. It couldn't hurt to talk to your local station, but help there is not likely, and not because they are unwilling to fix a problem, but because it is very difficult to them to fix a problem that they likely don't have.

    A good place to start is the local threads in the HD reception forum for your city over on AVS.

    While the problem seemed to have gotten better, we noticed it in abundance during the AI finale Wednesday night. This is so frustrating! :mad: Does anyone know a contact at FOX4 here in Dallas? They aren't responding to my emails.

    Thanks

    I noticed the glitches on the American Idol San Francisco feed via OTA antenna (2-1) with the HR10-250 (HDMI Cable). I also have Comcast HD with their 6412 III box and they had the exact same problem with their broadcast (component video cables). Based on this I think we can say that at a minimum it was the local Fox Feed causing the problems and since others are reporting similar problems with different local affiliates, that it was more likely a national feed problem.

    SF gets a west coast feed, and Dallas/Arlington gets the east coast feed, so the problem (assuming it is the same problem) is not related to a specific net feed. Arizona gets yet another feed, and AFAIK there were no problems there. With this many people watching, there certainly would have been a huge outcry if folks were having this issue, and we have heard nothing of the sort here.

    Both CA and TX stations (as well as AZ) pass the FOX feed directly by virtue of an MPEG splicer, so very little can happen at the station level to cause this other than specific transmitter/exciter issues. There has not been a splicer problem for many months.

    It is hard to rule out local reception issues, even though they seem coincidental. It does seem a little disturbing that an O&O station won't respond to your emails.

    On the other hand, a quick perusal of the last few weeks of this thread:

    http://www.avsforum.com/avs-vb/showthread.php?t=529070&page=1&pp=20

    indicates that there are more than a few folks who are experiencing this from KDFW. Not enough to indicate for sure that it is a station problem, but enough to make one suspicious. It may well be that they are having a continuing problem, and that all that can be done is being done (some times these things move slower than anyone wants, including the local engineering dept.). But, it would behoove them to at least fess up and dialog with those who call in reporting the problem. Most stations are happy to accomodate. I'd keep after them.

    Well, I can chime in and say it's not a Fox network problem. Here in Minneapolis, KMSP 9-1 comes with 100% reliability. Does everyone in DFW experience this problem? If not, then by far the most like cause is a reception problem. What digital channel is the station broadcasting on? What kind of antenna are you using to pickup the signal? What is the terrain around your home? Those are all things that can affect reception.

    Here in the Minneapolis area many people had problems with the ABC affiliate, KSTP. They broadcast on digital channel 50. I've never had a problem, however on the local forum, hdtvtwincities.com, lots of people blame the station for their reception problems. In many cases getting a better antenna or relocating it solved their problem. The station's engineers have even made a house call or two to review the situation.

    They also posted that the station could be harder to pick up because they share an antenna with two other stations, one broadcasting on channel 35 and the other on channel 32. They indicated that since the antenna is optimized for mid band and since they are broadcasting on channel 50, it made it slightly harder to pick up the station.

    There was also a situation with the local CBS affiliate, WCCO which is on digital channel 32. Panasonic TVs were having dropouts on a regular basis, but only while watching WCCO. Panasonic actually sent some technicians to peoples homes to take measurements and worked with the TV station to find the problem. It turned out that there was something slighly off in the TV station's transmitter. Once the manufacturer learned of the problem, it was resolved. I was pleased to see how all three companies worked together to solve a problem that only affected a small number of TVs.

    Good point. Unfortunately, that is becoming more prevalent. TV stations usually do QoS by erecting their own antenna and receiver, or demodulator. But in the era of DT that may not be enough. Common sense says that if they can see the signal without problem then there should be no problem for customers who have a valid reception system, but sometimes these little digital problems only manifest on certain types of reception equipment, and if the station is using something else, they won't know of that particular problem until someone else alerts them.

    FYI, the SF FOX affiliate, KTVU, does not air the west coast feed (for prime-time anyway) -- they record and replay the East feed (in both SD and HD). Why? Well, they have their own way of doing things ...

    That would be highly unusual since there are regional spots sold for each feed, which would be going against the wishes of the regional sales strategy of FOX. But then we are talking about SF, where they actually tried to move the start time of prime a few years back.

    It is unusual, but trust me, that's what they do. I've been in there and watched them do it. They've been doing for at least 15 years. As far as I know, they have permission from the network. Whenever there is a long movie, they start it early (at 7:30) so that it will end at 10pm and not disrupt their newscast.

    BTW, the CBS O&O in Sacramento DOES start prime-time an hour early, at 7pm. Been doing it for years. Don't believe it, check their programming schedule:
