HD? Not there yet

    I did some interesting calculations:
    - I noticed that overwhelming majority of Blu-ray releases want to be true to the cinema format so they are no longer released in 16 : 9 (1 to 1.78) but in 1 to 2.5 (that is an equivalent of 16 : 6.4) or higher.
    - There are no production, large 1080p screens (65” and higher). There are only promises for next year with undisclosed (probably exorbitant) price. So you’re stuck with 720p (unless you want to take the projector route).
    - When you watch the new BD movies, you get the large black bands. Since the screen cannot show anything more than 720p the effective resolution of what you’re seeing is 1920 x 512 (do the math yourself).
    - The resolution of a standard DVD is 852 x 480 and they are mostly sticking with 1 to 1.78 format so practically there is no image quality difference watching a BD movie vs. the corresponding DVD on a 720p screen. I do not think that most of us really care about the part of the original movie format image that we loose when cropped to 16 : 9 format. I trade that anytime for not seeing the black bands.

    What is the point of this post? What does it have to do with AnyDVD HD?

    I don't even know where to begin with all that's wrong with what you just posted there. I'm just going to simply say that I am VERY happy with my HD experience and then keep my mouth shut on this one.

    Well i'll take a stab... even though it's grossly off-topic.

    1. Movies are shot at *many* different aspect ratios. For example:

    Children of Men: 1.85:1
    Goodfellas: 1.78:1
    Casino: 2.35:1
    Troy: 2.4:1

    Actual 16x9 (1.78:1, illustrated by GF above) is fairly rare. In order to take a 2.4:1 movie and fit it into a 16:9 AR, you would have to do one of two things:

    -zoom and crop, which means you lose the right and left edges of the screen

    -stretch the movie vertically

    Neither options are acceptable. You will hear the term OAR (original aspect ratio) bandied about, and for good reason - it's the only way to see the movie as it was intended by the director.

    2. I'm not sure what point you are trying to make here... Panasonic, Olivia, Mitsubishi, and Sharp have 65" 1080p displays. Are you talking about projectors perhaps?

    3. I own a 46" 1080p display and the effective resolution is much higher than this. While your math may be correct for 720p displays, it's much different for 1080p displays. The point is still moot given the next fact:

    4. About 95% of the standard DVDs that I own are presented at OAR, so the difference between SD-DVD and HD-DVD/Beta-Ray are quite significant on my 768p plasma, and stellar on my 1080p LCD.

    No offense, but I think you may want to re-evaluate your stance. I think you're assuming that all SD-DVD are mastered at 1.78:1, which is simply not the case.

    I'm not sure about HD discs, but the way I always understood DVD to work was that the video was always encoded at 720x480 with the pixel aspect ratio determining 4:3 or 16:9 format (0.9:1 or 1.2:1, respectively). If the original source material was wider than 16:9 (which often seems to be the case for theatrical films), the video on the disc has letterboxing-type (though smaller, obviously) black bars encoded as part of the image to account for the wider picture, ensuring the video will still fill a 16:9 TV horizontally.

    As I said, though, I'm not sure how HD discs work since the video resolutions supported by the HD-DVD and Blu-Ray standards are already 16:9 natively whereas DVD-Video used 1.5:1 that was resized accordingly. What do they do when encoding 4:3 content for an HD format? Pillarboxing? Seems kind of a waste... maybe they should start manufacturing 1920x1440 displays for watching movies made prior to 1955, the many independant/small-budget films before and after the advent of widescreen, and the majority of TV shows.

    The only bit interesting in your post is your confusion about aspect ratios and pretty much everything else.
