  1. Re:DVD-Audio != AC3 on Burn a DVD-AC3 Compatible CD-R · · Score: 1

    At this point, almost every DVD-A capable player outputs analog only. Unless you consider a down-converted 44.1/48kHz 16-bit stereo PCM bitstream to be DVD-Audio. There are a couple of decks that output a proprietary bitstream that can only be decoded in a receiver from the same company.
    Fortunately, a standard has been finalized by the DVD Forum. It uses Firewire (aka IEEE 1394) to transmit full-resolution and sample rate data to the decoder of your choice. Here is a decent write-up on the new standard.
    My advice? Hold off on any new purchases until we start to see a good selection of products that support the new standard. And for the love of god, don't buy one of the proprietary products.

Why would you, when the Parhelia can do it without breaking a sweat?

    Well, a good psycological thriller gets in your head and makes you think... like momento did. I really did not have to think that much for this film. It was soooo predictable.
    I suppose I should have defined my terminology. You seem to think that "psychological thriller" is just a synonym for "crime thriller." The heart of a psychological thriller is not its unpredictability. The heart is its character's mental state, and personal (or interpersonal) conflicts.
    This movie could have made you think. You just tried to think about the wrong thing.
    How do you define a good person? Do the consequences of his actions determine his value as a moral agent (as Dormer says, do "the ends justify the means")? Or is it the actions themselves? Can Dormer be redeemed? Does he need to be? Did Dormer mean to kill Hap? Is Dormer any better than Finch? Would you have done any differently (in responding to Finch's offer)?
    I'm not suggesting that any of these questions produce serious discussion or insight into the film. I'm just saying that these are the types of questions that are interesting in a film like this, not "Is he going to catch the bad guy."

    You missed the point. Insomnia wasn't meant to be as "cool as [...] Memento." Predictable? Once again, not the point. Insomnia is not a mystery. It is a psychological thriller. In other words, what's going on in Pacino's (and Williams') head is what drives the film. Even more importantly: This is not a "good cop gone bad" movie you fool. Pacino is not a bad cop. He is a decent human being with a moral dilemma. That is the point of the film.
    All that being said, I'd recommend checking out the original (available on Criterion DVD). I preferred it (only by a small margin) to Nolan's version. This is probably because it was more subtle (it didn't need a big gun battle at the end), and possessed a morally ambiguous ending.

  10. Re:Actually: on Red vs. Blue Lasers Complicate DVD's Future · · Score: 1

    If the numbers you've provided are correct, then 1080i requires the highest bit-rate by a large margin. 1080i requires exactly 6 times the bandwidth of NTSC. 720p requires only 2.667 times the bandwidth of NTSC. Whatever the case may be, HDTV clearly requires many times the bandwidth of an "equivalent" NTSC signal. None of this changes my original assertion: a red laser (9GB/side) DVD cannot possibly provide enough storage for full-length HD movie. Unless of course you destroy the image fidelity with excessive compression or filtering. So basically the DVD Forum has destroyed any promise HD-DVD might have had. This makes me very unhappy.

    - NTSC -
    ((480/2)*720) = 172800 pixels/field

    It seems to me that the only people that want blue laser technology are the people developing it and videophiles. I fall into the latter category, and that's why I'm angry about this decision.
    The studios don't want it for two reasons:
    • The cost of manufacturing discs will go through the roof. The studios will have to eat a good chunk of that cost if they want the consumer to accept the new format.
    • The new format will mean they'll have enough room to store HD content at current compression levels. In their minds, this is a bad thing.
    The hardware manufacturers don't mind because they're going to be selling new equipment in either case. I'm sure they'd rather be selling new equipment that uses the blue laser tech they've spent so much money on.

    I'm angry because HD-DVD is basically the holy grail of home theater, and they're gonna blow it. This whole "improved" MPEG-2 sounds like crap. Filtering before compression?!? ARGH! What the hell is that? Apparently they have no regard for fidelity. In my mind it's a very simple issue: uncompressed HD content can occupy as much as 3 times the space compared to non-HD content (720p signal versus 480i gives (720*2)/480 = 3 or 1080i vs 480i gives 1080/480 = 2.25).

    If they keep red lasers, they're going to have to compress the data three times as much for 720p and 2.25 times for 1080i data (as compared to 480i). I don't care how good MPEG4 is, it isn't good enough to achieve that without throwing out some data. I don't even want to start on what MPEG2 would have to do to the data to fit it in the same space.
    So while technically we're getting a lot more resolution, what does it matter when we're throwing away so much data?

    I see two questions that arise from this:
    Can art exist alongside commercial success?
    Can the media use satire as an effective weapon against itself?

    First, I refuse to accept that money and art are mutually exclusive. I want to believe that art can be created regardless of the financial circumstances. Movies cost money. And if your art is intended to attack popular culture you can't make an indie movie because you'll simply be "preaching to the converted." Movies cost a lot of money, so let's move on folks! You can still say something important even if you're backed by a major studio (so long as you're Stone, or someone else with a lot of pull in Holly Wood).

    Second, I do believe you can use media as a weapon against itself. What Stone did with Natural Born Killers is a perfect example. He took a brainless, violent script from Tarantino (exactly the type of director he despises), and twisted it. He used this script to create the largest piece of performance art ever attempted. He used graphic violence, and sensationalism to draw huge crowds into theatres. He then proceeded to attack the very thing the audience was there to see. They were the perfect example of what is wrong with our culture today. And they ate it up. But the people Stone wanted to speak to didn't get it. They couldn't see past the violence. Most people were incapable of stepping back from the situation and seeing what Stone had achieved. It was a brilliant satire, but one so deeply buried below the violence and spectacle, most couldn't be bothered to dig deeper.

    Ultimately Stone's experiment failed. Not because it wasn't what he had envisioned, but because most critics and 'thinkers' have so little faith in our commercial artists that they refuse to give them the benefit of the doubt. In their eyes Stone was guilty of the same sin he was chastising other directors for. The important distinction is that instead of simply creating a violent movie, he had held a mirror up to Holly Wood, and our culture in general. It was a reflection that most didn't care to see.

Of course it "proves" nothing, because clearly, the proof you're talking about is absolute proof (as in mathematical proof). That level of certainty is unachievable in anything but mathematics. In matters such as these, the best we can ask for is reasonable certainty. And 90% is about as close as you're going to get.

    These "findings" certainly don't disprove Creation, because creation is about the "why", not the "how".
    This statement is grossly misleading. You're appealing to our sense of religious freedom: "Well... why not let them have Creationism? After all, it's about why not how." This is a lie. The How is exactly what Creationism is about. Religion is supposed to answer the Why. Creationism has never purported to answer the Why of our existence, only the How.
    Don't defend Creationism by treating it as some sacred cow. It can and will be attacked. Why? Because it makes claims directly related to the field of scientific inquiry. It must therefore stand up to scientific standards.

For a black hole of roughly 30 solar masses that has no infalling matter it would take 10^61 times the age of the universe to evaporate. Black holes with mass less than 10^11 kg can evaporate in less than the age of the universe. [Ref]
    Hawking radiation isn't really energy escaping the black hole as that is not allowed for by their very definition. The event horizon is defined as the point at which the curvature of space-time becomes so great that not even photons can escape its pull (not a strict definition I know, but a functional one at least).
    HR is actually something which occurs on the "surface" of the black hole, at the event horizon. It involves Heisenberg's uncertainty principle, and particle/anti-particle pairs as I undertand it, but would not venture an explanation as I am sure it would be sorely inadequate.
    As far as photons travelling at a velocity greater than c, I don't know what to say. I'm under the impression that our current understanding of physics indicates that superluminous velocities under any circumstance breaks a lot of what we think we know about the universe (especially special relativity and I think parts of general relativity). What effect that would have on black holes (their very existence in particular) I wouldn't want to guess.

One can select between genes on chromosomes, codes in a computer, or ideas in a culture. As long as mutation, replication, and differential survival occur, any substrate can be selected. For instance, ideas can change (mutate), they can spread (replicate), and some can die out while others persist (differential survival), so we would seem to have a substrate suited for selection.
