Hi Gunther,
While many of your points about DTV are correct the fact is this change was basically forced upon all of us. We all have paid for it with partially funded converter boxes, new TV's, higher cable rates, etc, etc. And this doesn't begin to touch on things like the hundreds of thousands of wireless microphones thrown in the trash because DTV signals interfere...has your place of worship had to spend a few hundred or thousand because of this? And who benefits the most? The FCC, who made the decision that we needed DTV! They freed up a bunch of frequencies and then auctioned them off to cellphone carriers to the tune of billions of dollars!
And as far as digital being better, sometimes it is, sometimes it's not. Music for example nearly always starts analog (non-digital instruments, voices) and can only be heard in analog (ears). If you go to the pickiest audiophiles they listen to their music, even today's latest recordings, on vinyl LP records! Why? They sound better. Digital recordings are cheaper to make, more convenient to carry around, but they are not an improvement in quality for us listeners. And when we were pushed into cassette tape use we saw how the industry was happy to horribly degrade quality to increase profit (Phillips invented cassettes strictly for use in dictating machines). The same is now being done with "digital cinema". Test after test has shown that the very finest DC equipment approaches the lowest quality 35mm film projectors so the industry rushes to install it (because they can cut staff and have more and higher paying pre-show ads) and tells us "it's better, it's DIGITAL!" don't believe all you read.
