Dish, KOB-TV, dropouts
Gentlemen, for what it's worth, I watch NBC in ABQ over the air (digital), and I've had trouble lately with prime time shows like "Life" having serious problems. I do not know if it's a reception problem or some kind of encoding/decoding thing, but it's looking more and more like the kind of phenomenon you get when you grab a video file from the internet and try to watch it before it's fully downloaded. The artifacts seem more complex and hallucinogenic/psychedelic than the simple blockiness and dropouts I get from a misaligned antenna.
So.... I wonder if that's what you're seeing on your Dish... badly decoded or downloaded video (I'm assuming KOB gets the feed earlier than the air time).
I hate to blame the local guys for this, but I'm wondering if Dish has no remedy for this other than to hope that KOB learns how to run an HD station. If a wind warning for some tiny corner of New Mexico is issued, we get to have a minute or so of downsized, non-HD programming with an obnoxious crawl and map superimposed. With all the DVRs in use now, these "breaking weather bulletins" are a big waste of time. I might as well be watching Weather Channel reruns.
I see great irony in the fact that they are switching off the analog soon (and working like hell to get everyone migrated), but they still can't produce a trouble-free digital experience.
