No, it's not an HDMI cable that at issue, but an HDMI socket. The original Xbox 360 has only component video outputs.
At present, the Component outs are capable of 1080i (or even p). But the HD-DVD spec includes a scheme to downgrade the effective resolution to 540p, if the poor sap of a viewer is using the unencrypted, insecure component connections. An HDMI socket would bypass this issue.
The other point is that HD-DVD and Bluray both allow lossless soundtracks-- akin to the difference between a CD and an MP3. However, the Xbox360 only had a spdif or coax connection, which lacks the bandwidth required for multichannel PCM. HDMI does, assuming you've got one of those newfangled receivers. (The HD-A1, a consumer HD-DVD player has a multichannel analogue output as well).
The AUDIO_TS folder is for DVD Audio players. It contains an entirely separate menu structure.
For instance, if I stick my copy of "R.E.M In Time" in my computer's player, the setup menu allows me to choose dts, dolby 5.1, or dolby 2.0. If I play it on my Oppo, the setup menu allows me to choose "Advanced Resolution Stereo" or "Advanced Resolution Surround."
Wrong. In most areas, the VHF spectrum is already allocated, so when dtv assignments were made, most stations received a UHF frequency. When analog TV is killed off, the stations will have to give back one of their assignments. For various reasons, some stations will keep their old analogue assignment, return the digital assignment, and broadcast DTV on VHF. Those stations currently broadcasting on channels 52-67 will be assigned new channels in the 2-51 range, and the 52-69 spectrum will be reassigned by the FCC for other purposes.
US television channels are 6MHz wide, whether analog or digital. If it's digital, the broadcasters use a scheme known as 8VSB to squeeze 19.2 Mb/s out of it. This datastream can be subdivided any number of ways-- a common configuration is one 1080i main channel, and a 480i weather channel, but some PBS stations have four or more 480i channels.
Digital signals can be backed closer together than analog channels.
For instance, in my market, the analog channels were 2,4,5,7,9,11,13,14,20,22,24,26,32,45,50,53,54,56 and 66
notice that most of the stations are nonadjacent to avoid interference problems
But digital signals are not as susceptible to this kind of interference. So a major metropolitan area with 20 or more channel assignments does not need 400 MHz of spectrum, It might need only 150 Mhz. The spare bandwidth can be reallocated for other purposes (including the so-called "first responders" who are angling for a nifty communications system that works inside steel framed buildings) and sold. The proceeds from the spectrum auction is supposed to pay for the "billion dollar handout".
It's just like privacy. Can the government read your mail and tap your phone. Yes. Can you read what the government produces on your dime? Not on your life. Why that would invade the privacy of the republic.
AACS isn't CSS. It's not based on a ultra-1337 sekrit crypto algorithm. It's based on a published, well documented cryptographic engine (AES). The number of possible device keys is not limited to 400 or so-- millions can be released, and millions can be revoked.
There seems to a widespread belief that no one in hollywood learns from their mistakes.
I would like for HD-DVDs to be accessible for fair use. I really would. But I see no evidence that this breach cannot be repaired by AACS and the DVD forum.
Besides, HDCP is breakable. Not unlockable with a spare key that someone found lying under a doormat. Breakable. Somewhere around 40 displays are required to locate the collision, and if you ask nicely, and promise to bring it back in one piece, I might just donate mine to the cause.
In the United States, a HDTV is not required to have a HDMI port and not required to use HDCP. There's a HDMI logo, which is supposed to guarantee some compatibility, but apparently the technology doesn't work. Maybe HDMI 1.3 will fix this.
Fine. I want you to take an HD-DVD, decrypt it, and play it on (pick one)
1) your ipod 2) your bsd laptop
Well?
Have you done it yet?
Quickly now. You don't want to find out that by the time your tool chain is constructed, and you're ready to start buying HD-DVDs with abandon, that keys have been revoked and security flaws patched.
I'm guessing that there are perhaps a hundred HD-DVD titles, perhaps more, perhaps less. Not a whole lot. The keys discovered so far were recovered with the help of an insecure player, which may have its access revoked until it is rewritten. CSS had a fixed keyblock that only allowed for a few hundred different keys. AACS uses a broadcast encryption scheme that allows hundreds of thousands of keys to be revoked.
The reason that keys can be revoked is to prevent the use of players which have security holes in them. The affected player will undergo a substantial rewrite, and any any embedded keys will be themselves encrypted. But, hey, they could make the same mistake twice.
I just don't think that the ability to decode a limited number of HD-DVD titles is worth it. Fair use is about freedom-- the ability to use copyrighted works in ways not envisioned by the original copyright holders-- criticism, time shifting, parody, space shifting, news reporting, educational use.
But this? All it really does is allow owners of PowerDVD or WinDVD the ability to play a limited number of works from the hard drive. Big fucking deal. It's not freedom. It's not the first step towards a linux HD-DVD player. It's the first step towards a key revocation, the first step towards a rewrite of whatever player leaked the keys, the first step towards even more onerous DRM requirements, maybe the first step away from HD-DVD towards Bluray.
But, if you want to distribute the movie on the internet, it's useful.
Yeah. Someday I'll write a post simultaneously defending the private possession of military grade weaponry as an insurance policy against tyranny, and proposing the canonization of RMS-- and all of those karma points will come rushing back.
Televisons have had hdcp for a good long time. I suppose it took the computer industry some time to catch up--probably because no one was daft enough to think that encrypting the video link from a computer was terribly useful.
How long is it going to be before PowerDVD or WinDVD is patched to stop the leaky key? Congratulations, you can play "Serenity" on your Myth Box. Will you be able to play "Return of the King?". Or "Children of Men?" Or "Empire Strikes Back?"
DeCSS was important because the encryption algorithm was unknown. This? All it does is demonstrate that if the keys are known, the disc can be decrypted. Big Deal. That's how every encryption algorithm works. That's how every well designed lock is supposed to work. If you have the key, you can enter. If you don't have the key, you shouldn't be able to open the lock, even with the help of detailed diagrams and specialized tools.
The central tenet of the free software movement is not "slavish dedication to RMS's whims." It is that software should not be designed in a manner that restricts our ability to tinker-- to enhance, fix bugs, and redesign according to our own dictates, and not according to the whims of others. Accordingly, there should exist software that reflects that ethic.
Most of the DRM schemes are incompatible with a free operating system. Many require that signed drivers be used. This would tend to restrict the right of the owner of that system to hack the driver, so as to add features or remove bugs. A user would have to rely on the creativity and expertise of another individual, and not on his own programming skills.
RMS may be a good programmer, and a charismatic philosopher, but the decision to follow his dictates must be based on whether his arguments are sound. Blind obedience to RMS is just as distasteful as blind obedience to Microsoft, Apple, MPAA, the RIAA..
I can see a future in which DRM actually succeeds. Unfortunately, it would come at the cost of anonymity. (universal digital signatures-- if you wanted to install your own drivers, the drm system would accept your personal signature, and embed it in a watermark. Piracy could be traced, copyright violations prosecuted, but noninfringing use would remain.)
In some cases, if you were disappointed in the packaging of a disc, you could always go over to their "Import" bin, and see if they had a Japanese version.

All HD programming have no bars. They are formatted properly.
Not if it's a 'scope film like Star Wars.

There are others, but unless you have a very fancy projector setup (constant area projection), you're still going to get mattes.
