This is exactly why I've told my family, friends, and anyone who will listen, to do the homework first. Find out exactly what you want before you ever set foot in one of these places and only go there to buy it. Too many people buy televisions because of the way they look on the showroom floor (I used to do it, too!) And people like my father, God love him, will tend to believe the blue shirts (or red shirts) just because he doesn't know any better.
The best thing we can do is spread the word far and wide, to anyone who'll listen, that these guys don't know what they're talking about. They just want to sell you something before you leave and will make up stuff on the spot (I recall looking at HDTV's at Best Buy and asked the guy to show me an anamorphic dvd so I could see what it looked it. He basically looked at me with a dumb stare and went, "huh?")
If anything is going to hurt the digital transition, it's going to be these type of CE outlets that make it so confusing, complicated, and expensive for the average consumer that they won't ever want anything to do with it.
We fear what we do not understand.
