One thing I have learned is thick skin, it didn't come natural that is for sure. Yes, you are correct, on fast moving objects, it should respond better.
Broadcasters are having to learn the consumer end of the business, it's not like it use to be. There is a difference in TV's and receivers, not only is it looking for RF but PSIP information as well. If the box doesn't understand the PSIP, it won't pick up the digital signal. You can move the antenna all you want, it may not mean a bit of difference.
The downside of a broadcaster is that you have comments on the different digital streams to cable companies, you can't just go around flip flopping channels around. Bandwith is bandwith and you just have to work with what you got.
I am learning alot about the problems on the consumer end, it will help us address issues that we normally don't see. Thanks to this forum, I am more aware of the issues viewers face.
