The problem is manifested across the vast majority of our society. When the VCR came out what was the two biggest complaints? 1. The damn clock keeps flashing (people didn't or wouldn't take the time to learn how to use it) and 2. the damn red, white and yellow connection thingy-bobs were confusing. Worse, along came s-video and more confusion. All EVERYBODY wanted was the"good old days" when you connected your antenna or cable to the RF connector.
My parents are a great example of what the problem is. They purchased an HD television on my recommendation. DirectTV came out and set up satellite and voila! HD right? Wrong!! But they believe they have HD and well, "if this is as good as it looks, what's all the hub-bub, Bub?" I schedule a visit and sure enough, the HD from the technician is an S-Video cable. The STB isn't even set to output greater than 480i and certainly not in widescreen. I fix that with an HDMI cable and provide the setup.
Next, I get them an HD-DVD. They don't understand why I have to get them a special cable when they've got a drawer full of those damn red, white and yellow video cables in the drawer!! I have to go into full explanation mode.
Next, they get a sound system I recommend and once again, there's those pesky different digital connections. Again, "what do you need a special cable for when I have a drawer full of those damn red, white and yellow cables?"
Now, finally, they're all set up. But wait, there's a remote for the TV, the STB, the HD-DVD, the VCR (still has to have tapes!!) and the receiver. They can't use anything (they're so confused and exasperated!) , so I get them a Logitech remote and program it for them. They're happy they have such a technically adept son. However, I come to visit them and they're watching the low def analog channels. Why? The OTA antenna from DirectTV was never installed, so another call to those guys for scheduling this. Finally, it gets put in place and now they have the local HD channels, right? Well, no. The program guide information shows up for the locals only on the analog feeds, so when they scan through the guide, they see what they want and press okay. So now they are watching the analog feed totally unaware that the same programming is a click up or down in HD.
Sigh!!!
So, what we have are connectivity and ease of use issues that are an impediment. Components should all talk to each other, have a handshake and an agreement about what is the best settings for the attached equipment and then everything adjusts itself accordingly. Total ease of use. Dummy-proof. That's not going to happen, though, and moms and dads, grandmothers and grandfathers all across the country are blithley going through this world in complete ignorance of everything that needs to be done to get great sound and a great picture and for all that, they just really don't give a hoot, and THAT, my friends, is what is going to keep HD as an enthusiast level product. At least until HD is force fed upon all of us and connectivity and simplicity are synonymous.
