Ok, talked to Bob at KKTV. He said he just got back from vacation, but speculated that any weird format changes like the one Vaggeto described are most likely due to "operator error." However, he said he would look into what happened last night. BTW, he said that KKTV missed the feed today for the HD broadcast of The Young and the Restless.
So, it just appears KKTV is having growing pains. He said they're trying to get all of their engineers up to speed on the new technology as soon as possible.
In the meantime, he agreed that if WE notice a problem with the signal, we should immediately call their engineering staff so that it can be fixed. Their number is 634-2844 (ask for Engineering). After hours, you can still call that number, but you just have to enter in an additional extension for "news emergencies" and once again request to be patched through to Engineering. I think it's 243 if I remember right (the prompt tells you, either way).
Although this is sort of trivial, I told him how I wish KKTV would only turn on the HD broadcast flag that my SAT520 picks up for true HD material, instead of all programs like they are presently doing. He said he would look into whether this has to be done manually or can be preset.
Last but not least, he expressed my sentiments regarding the current policy of zooming and cropping 4x3 upconverted material. He said he was going to try to convince Tim that they should leave 4x3 material as 4x3 and let the viewer decided if they want it zoomed and cropped (provided, of course, that your display or receiver can do this).
Cheers!
