A good HD broadcast in my light controlled dedicated theater totally annihilates any DVD. Not even close, are you kidding me. My HD broadcasts are had for free, via OTA.
No, not kidding at all. I was reminded about LotR was on TV (TNT-HD I believe) and I caught myself watching it. When the commercial break came, I grabbed my DVD copy and threw it in. I was impressed with the improvement in picture quality.
There is a greater percentage increase in horizontal lines of resolution between Bluray and DVD, than there is between DVD and VHS.
Sure, but do they matter?
If I had a ten-million pixel format and I offered a two-billion pixel format that would be a bigger increase (as a percentage or linearly) than from an old B&W TV to HD, and yet the subjective improvement would be far smaller.
Image resolution always faces the issue of diminishing returns. Further: how much better will my MASH or Twilight Zone images come out? One cannot create new information.
I think there's too much emphasis on pixel count. There was/is in cameras as well. I have a 6MP digital camera that I would not dream of trading for whatever the bottom of the 10MP cameras are now. Why? Because 6MP is more than enough for the size prints I am making, and I would not giver up my lenses, optical zoom, and optical stabilization for more pixels.
Similarly, I'll take the DVD of Fifth-Element against the first BluRay version any day. The much better transfer outweighs any "advantage" of putting out a low-quality resolution to a screen with a lot of pixels (the later edition of the BD is better). Similarly, I would not pay $10 extra to get 1080p over 720p on, say, a 27" TV I was going to mount on a wall.
No. DVDs will die not because of an advantage for BD, but because of a lack of an advantage for DVD. Right now the DVD advantages are:
- They are cheaper.
- There are more on the used market (which are also cheaper)
- The players are cheaper.
- Most people already have a player.
- There are more movies on them.
- More software will edit DVD-quality.
- DVD burners are cheap
- More software will output to DVD.
- More computers are capable of doing reasonable-speed editing and compiling in SD.
Bluray is the first video format for us that offers lossless mch. The impact for me is that for the first time in my life am I watching classical music concerts in mch. With any* DVD ever that I have watched, the 2.0 PCM track was always superior to the lossy mch with concert discs.
You aren't really having a debate on the question at hand.
You seem to be answering "which characteristics will make me want bluray's over DVDs in some situations" when the question was about DVD obsolesce.
I would further point out the extreme advantage of DVD-A over CD, and the continued existence of CDs (and CD-based download-able music).
