Blu-Ray?

[Adam And Eve]

What is the difference between Blu-Ray and HD-DVD?

I mean, is there a difference between quality or something, which is better? o.O

[FreshLaundryX]

HD-DVD is supposed to be better quality, but I'm sure Private Joker will jump in here and quote a bunch of horse crap that would prove otherwise.

Blue Ray can hold waaaaay more information.

PJ also claims Blu Ray has better audio quality, but I have yet to hear that elsewhere.

360 Add-on Drive = HD-DVD
PS3 Bulit-In Drive = Blu-Ray

we have yet to wait till he comes in :]

Depends on a number of factors including the actual player being used and the compression method used to fit it on the disc (MPEG-2, H.264 also called MPEG-4 and VC-1 also known as WM9.) Blu-Ray technically has a faster transfer rate with bit rates on up to 54 mbps. Honestly, most "qualified" experts will tell you there is usually very little difference between the two formats in terms of image quality and again it depends on player, transfer etc. Just because Johnny Blogger says he likes product x over product y because he tested one movie on both formats on one type of player for each doesn't mean much lol.

Forgot to mention audio. Both formats support the following:
Dolby Digital
Dolby Digital Plus
Dolby TrueHD
DTS
DTS-HD
Uncompressed PCM

Actually the Blu Ray and HD DVD have IDENTICAL video quality. Blu ray has better sound...the PCM 7.1 lossless uncompressed audio is better then the digital TrueHD that both HD DVD and also Blu ray have. (HD DVD is not capable of PCM due largely to the laser and the limited storage capacity).
The digital transfer of a Blu ray movie's video is the same as a HD DVD, its identical essentially. The real problem is having dueling formats, and the inconvenience of not having access to all new films. I personally believed in HD DVD at first, until I actually got a PS3. The capacity of Blu rays is really what gives it its longetivity (supposedly the transfer quality is imperceptibly better due to the size of the blue laser) if you think about it, the disks come standard dual layer at 50 gigabytes, and are capable of 8 layers at 200 gigabytes. It will be a long time before people will be able to DL films and say, have handfuls of spare 50 gigabyte spaces on their hard drive, let alone build a film library!

I can't help but to feel that the Blu ray was once again Sony's greedy foray into creating their own proprietary format (which historically has always failed). Microsoft's released of HD DVD was obviously created to compete directly with Blu ray, thus neither company is necessarily easy to sympathize with. As it stands the Blu ray will probably win the "format war", and justly so, its the cooler product with better potential.

Thanks for being so thorough. If I am not mistaken uncompressed PCM is only on Blu ray.

[CherryIcee]

Technically HD DVD does support uncompressed PCM. It just isn't widely used on that format because of a 2 channel limitation.

Do you mean theoretically?? Show me a HD-DVD that supports PCM.

PS- PCM on a 7.1 channel surround system with a fiber optic hook up is amazing. I have actually stopped going to the movie theatre and watch blu ray instead. ;)

[CherryIcee]

It's an industry standard. ALL HD DVD players are required to decode linear (uncompressed) PCM. I should note that because of bandwidth requirements, lossless audio on HD DVD is generally Dolby TrueHD however.

PCM is slightly better then TrueHD (something about generating discrete sounds), and most Blu ray movies audio is in PCM 7.1. Most HD DVD and Blu ray discs that are on both platforms have TrueHD.

I know, I was simply pointing out that all HD DVD players do in fact have support for LPCM (Linear PCM) as it is a requirement for any hardware that carries the HD DVD logo. Basically I was correcting your statement that HD DVD doesn't support LPCM (which it does) but because of the higher bandwidth requirements for LPCM, it is not really used as it would generally be restricted to 2 channels, so instead the lossless audio of choice for HD DVD is generally TrueHD.

Heh, wait until TeraDisc becomes the defacto standard. With the transition to the blue laser system, they estimate up to 5TB of storage on a single disk. Heh, imagine entire series of shows in 1080p on a single disk. No more swapping out disks like I have to for my current sets of TV series :D

Almost forgot about the 300GB Holographic disks that are available now as well as HVD (which uses a green laser.)

Blu-ray looks and sounds cooler.

I'm not that much into the technical details of HD DVD and BluRay as PrivateJoker and CherryIcee, but: Aren't those two just data mediums? I mean, yeah, the players currently support this and that, but couldn't that change?
That said: Given both mediums were filled with data using the same encoding, BluRay should be able to store more data, or the same data in a higher quality, simply because it has a bigger capacity.
What I'm trying to say is: currently there isn't much of a difference, except for the very few true audio / picture quality geeks out there, but BluRay should have a bigger potential for better quality simply because it can hold more data.

Smaller disk. FTW.
