AACS is the copy protection implemented for the data on the disc and is not related to HDMI. HDMI/DVI use HDCP copy protection.

There are already HDMI/DVI to analog converters on the market... Not cheap currently, they range from about $300 to over $3000 depending on what type of conversion. I think either Gefen or Key Digital have a DVI to Component converter for about $450. However, due to HDCP licensing, none of these converters are going to work with up-converting DVD players and/or HD-DVD and BluRay players. It will take a non-licensed, illegal product to do that... Such devices may arrive someday on the grey market, but I actually doubt it. Not much purpose and this isn't where piracy takes place. The bulk of piracy occurs at the disc and data level. Pirates rip DVD movies onto blank DVD media, they don't use a DVD recorder to receive the signal and burn it to a disc... Most DVD ripping softwares produce inferior copies instead of 1:1 copies because of two reasons. 1> If they ever get hauled into a legal battle, they at least have the inferior copy argument along with the right to "back up" your investment. And 2> most DVD features are on dual-layer discs. Currently, even at bargain prices, blank dual-layer media isn't a whole lot cheaper than actually buying the production copy of a movie. At that point, you'll be paying $7.50 for a blank disc and will still have an inferior product vs. buying a pre-owned copy of the movie for $9 at the local video store. Hmmm....

Now, there are some grey market converters on the market that will take an HDMI / DVI signal and strip the HDCP protection. These are also expensive as they must decode and re-encode the signal, but they're popular with people who want to hook up their HDTV sources to a non-HDCP compliant display like that 24" Apple Cinema Display. Most new PC monitors are becoming HDCP compliant... Like all the Wxx07 LCD models from Dell are.

In the end, people will rip BluRay and HD-DVD discs to inferior copies and even 1:1 copying will be available in some form -- just as people do now with DVD. AACS will be broken in a short amount of time (there's already rumors floating around that it's been successfully defeated). There's no such thing as perfect copy protection... It's a continuous game where the content producers try to keep ahead of the hackers and the mean time can usually be measured in weeks. Maybe months in extreme cases. AACS at least has the ability to be upgraded... This is one of the key reasons why HD-DVD and BluRay players have ethernet ports on them and they can connect directly to the internet for upgrades. Upcoming movies can require newer versions of AACS on your player in order to work.

This isn't necessarily true. A proper digital source into a proper digital display will render a better image that most people will be able to see in a side by side comparison vs. the same material over an analog connection. Right now, most people can't see the difference (or at least not enough to notice without really trying) when comparing an HDMI feed with a component feed. Lots of factors come into play, but the unfortunate reality is that few HDTV displays out there are fully digital and most convert to an analog signal at some point before the signal hits the display. But on a true all-digital display, the difference between a component or VGA input and a DVI/HDMI input is night and day. If you have a fully digital capable display and can't see the difference then, you may want to investigate and see if the display truly is what it claims to be. Or you may need to get your vision checked, or there's something wrong with your digital source.

As for menu complexity, I can't see any theoretical problem with encoding the menu in MPEG2 and the main feature in VC1, or MPEG4p10.

Yep... No reason why the feature can't be encoded in a more efficient codec and leave the menus and extra fluff to still be MPEG2. I suspect that most studios are taking their time with software upgrades and aren't ready to really dive into something new. After all, look how far the quality has come with DVD over the past several years as the studios kept tweaking their MPEG2 workflows. I think we have a lot to look forward to in terms of quality with the new HD disc formats. Unfortunately, it's not going to happen over night...

Just one last comment to this thread for now...

Has anyone actually noticed that Sony isn't really trying to be sneaky with the fact that this recorder can't play protected content? Look at how this drive is being marketed... It's just a DVD/BD writer. It's primary function is for authoring BD media. ..Now go look at their other BD devices like the models in the VAIO desktops and notebooks... They do read and playback protected media as well as write BD media (although only single layer for now).

I think Sony has blundered the BluRay introduction about as badly as any company could ever screw up a new product launch and this drive is indeed only a half-baked product. But Sony has been very open and forthcoming regarding what this product will and will not do. So, on that note, I also think that the conspiracy theorists need to back off a bit. If this drive serves your needs buy it. If not, don't buy it. Simple.

To be honest I don't care too uch about being able to play content on a PC. However if this drive can't even play back the discs that you create yourself then there might be a bit of a problem!

I agree... But then again, I don't think this drive, or most other BD writers, are capable of creating AACS content at this time. If you want AACS I think you have to encode an image onto some other media and deliver to a replicator - just as people did with dual-layer DVD before DL recordable discs were available.

Sony Blu-ray Drive Now Supports Movies

I have been following along this debate between Blue Ray and HD DVD and here is my two cents. (Correct me if I get some facts wrong)

HD DVD is compatable with older DVD and will support playback of regular DVD.

Blueray cannot play regular DVD without an additional laser.

HDDVD uses exisitng production lines with little re-tooling.

BlueRay requires a new production line.

HDDVD is more durable.

Blue Ray is easily destroyed with it's surface information so vulnerable.

HD DVD 33 GB

BlueRay 50GB

Disk technoogy is a temporary step at best. Soon everything will be drive based. So why re-do all things just to create a new and temporary format. Oh yeah, that way the studios can make you buy your favorit movies AGAIN.

Correct. HD-DVD players can also read CD media.

Somewhat correct. They require additional hardware capability to refocus the laser for DVD compatibility. This adds greatly to the cost of the unit... Early prototypes and demo untis used dual laser mechanisms to provide DVD compatibility. Most of the first generation Blu-Ray players don't read CD media as an additional laser mechanism is required.

Correct.

It requires changes to production, but nowhere near as drastic as the HD-DVD camp would have you believe. In fact, Sony's Blu-Ray replication process is very cheap to buy into and economical to run. On average, Blu-Ray titles are $8 cheaper than HD-DVD titles when comparing MSRP. It's all protected under NDA, but a lot of industry watchers believe that Sony is keeping prices low by requiring studios to adhere to their pricing standards and while the Blu-Ray players are more expensive, Sony is trying to beat the HD-DVD competition with lower prices for movies combined with increased retail exposure. I'm not sure how Sony is going about it, but Blu-Ray exposure in retail stores is very up-front and highly visible. HD-DVD has since been pushed to the side at most stores.

No. And concerning durability, both HD-DVD and Blu-Ray just plain suck. Just as DVD is more sensitive to scratches and dirt, smudges, etc.. compared to CD. So are the new HD formats in comparison to DVD. Panasonic had it right when they started to put DVD-RAM in a protective shell. Sony did it right with XDCAM and UMD, but still opted for the bare 5.25" disc for BluRay since everyone is so familiar with these things.

Yes, and so is HD-DVD. :-(

HD-DVD = 15GB (about 14.5GB actual) per layer, max of 2 layers.

Blu-Ray = 25GB (about 24.2GB actual) per layer, max of 2 layers for now - Sony claims up to 12 layers with future revisions.

All formats are temporary, regardless of the media they come on. HD-DVD and Blu-Ray won't be the last disc based formats to come along. There will always be a need for a tangible media or storage method to place data files or movies or music onto. The spinning optical disc is going to be with us for a long time to come... The next wave of storage advancements will bring solid-state devices, holographic media and other exotic technologies demonstrated over the past several years. IMO, holographic media will be the next big storage advancment. It can work off of spinning disc type media or stationary media like something the size and thickness of a credit card. It could easily have multiple layers just like current optical media does, but instead of tiny little pits or grooves in a reflective film inside the disc, it would have holographic dots. Just like looking at a hologram, the image that appears 3D as it changes with the viewers' angle of view, a holographic media would present different data depending on the angle at which the laser enters and reflects off the data surface. Now you have a media that can have the same data density as HD-DVD or Blu-Ray, but the data presented for reading/writing changes with the angle of the laser. In holographic storage, if the read laser can change angles from 10 degrees to 170 degrees horizontally in 0.2 degree increments, and the data "dots" are the same as HD-DVD, then it would store 800 times as much data in the same space as HD-DVD!

Chinese counterfactors do not seem to know that !!! they sell bit for bit copies on dual layers for 2 dollars in most Shangai stores, where Single layers copies are charged only 1.40 !

When this happens, people will move to re-compresion... a good VC1 copy can sit on dual layers STANDARD DVDs ok...

Yes, but I was talking about blank recordable media. The Asian counterfeit market is a different matter -- those are actual factory replicated production discs, just like the real thing. Manufacture costs are literally $0.10~0.20 per disc and often that includes the case and wrapper.

Also true, but it's still a recompressed copy. And even the best VC1 encoded copy of an MPEG2 DVD stream is still a generation away and it shows. Many pirates are content with this and it's still a problem that studios would like to eliminate. But the primary concern right now is to hold off the 1:1 copies and keep new HD players upgradable to future methods of copy protection. In the end, the studios don't care if someone wants to rip 1:1 copies to a computer and play it from HDD because that's not a very economical solution for most people as they build a library of films and it will be a very small percentage of people actually doing such things. Oh, wait... Both BD and HDDVD allow media server use anyway, even on rented movies as the random disc verification doesn't kick in until a title has been logged for 45 days.

Replicated copies on the scale of shops in Singapore or China won't happen here as there's at least some real effort to enforce the law. But in the end, it's just like anything else and pirated copies of HD movies will be commonplace and there's nothing the studios can do about it except shrug their shoulders and move on to the next format.

[Pierre Barberis]

They coUld also charge a reasonnable price - in line with VOD , sort of 5/6 dollars. And give some credit if you already own th emovie on some older medium ( DVDS,,,) This wold absolutely kill counterfactors , at least in the westyern world, and probably their revenue would NOT be badly hurt, due to volumes sold at this price point !
