You're correct. Typo. Should have put "owns" in quotes. Wallyworld's exclusive agreements with Sanyo controlled what TV's were being produced and that's what I meant to say. The net effect was that analog sets were being made for Wal-Mart long after they should have been. Our local Wal-Mart wasn't even smart enough to put the required disclaimer on the analog sets until I pointed it out to management. It was a lackadaisical approach like this that forced the Gov't to impose a hard cut-off date.
Dear atrac - sorry for jumping on you and your "cause". It was an over-reaction to a number of people on this forum who imply that there's something wrong with you if you don't hear the "defect". I'm still convinced the audio problem is a signal problem and not a problem with the box. The fact that everyone doesn't experience it combined with the somewhat regular reference to a particular broadcast or station plus my considerable experience with similar problems with C-band leads me to believe that. I'll give you an example. Yesterday I watched the Phillies/Cubs game on Channel 56, Scranton/WB. During the commercials there was a very apparent second, background, audio running. You could distinctly hear the audio of a different commercial. Now I'm sure some tech-wiz could jump on that and tell us it's another example of the sound problem with the Zenith. It isn't. It's simply a broadcast problem and I believe the "chirp" or whatever you wish to call it is also. As I stated earlier, out of the almost 200 channels I receive on my C-band dish only one has this same audio issue and that is the national PBS feed on W4. The problem was there with my TI receiver and is still there with my 4DTV receiver. No amount of tweaking or fine tuning affects it.
I've been watching digital OTA for almost 5 years now and believe me it's come a long way. Just a couple of years ago I sent a letter to one of the network affiliates to inform them that their digital stereo signal was reversed. Right was coming out left and vice-versa. They fixed it. It just seems to me that taking the issue to the station might be more helpful than pounding on the Zenith box.
