Talk:Comparison of high-definition optical disc formats

message: "The plastic disc, with a thickness of 1.2 mm, would protect the information. Lenses could be used to focus on the pits without the dust particles becoming visible. The same happens with dust on the lens of a photographic camera or scratches on a window; if there are not too many of them, they fade just enough so as not to appear on the photograph." 
In this article, disc depth seems only to be discussed in terms of durability (resistance to the inevitable dust/scratches/fingerprints and protection of the data layer), not focal length (said inevitable damage being out of focus).
(Let me qualify the word "inevitable" by stating that I handle discs very carefully. I try to avoid touching the bottom surface of the disc, I keep my discs in their case or sleeve or other environ with minimal dust, and clean as needed. I am amazed at how infrequently I have to clean discs considering their tight spec and how much they can take before they become unreadable.) (168.28.44.159 (talk) 22:21, 28 January 2008 (UTC)
thread_title:  Disc Depth 

message: According to NPD, which excluded sales of PS3 or Xbox 360 units, the standalone sales of HD DVd and Blu-ray players are essentially tied.  49% HD DVD and 49% Bluray.
Revenue was 37% for HD DVD and 58% for Blu ray standalone players, due to higher profit margins on BD machines.  Link: http://formatwarcentral.com/index.php/2008/01/23/npd-confirms-huge-blu-ray-share-jump/
"Perhaps the most interesting news was the total numbers for 2007. While we have been lead to believe that HD DVD has had higher standalone sales all year, the NPD totals show the unit sales were the same for both formats, each with 49% of the unit share, however Blu-ray Disc players had 58% of the revenue compared to HD DVD with only 37%. The remaining 2% unit sales were the combo players, with 5% of the revenue for 2007."  —Preceding unsigned comment added by Theaveng (talk • contribs) 13:32, 25 January 2008 (UTC)
thread_title: 2007: Standalone HD DVD and Blu-ray Players are EQUAL in sales

message: There's a lot in the article about HD DVD vs Blu-Ray and how they stack up vs each other, but what about total home video marketshare?  Can anyone find a source for that?  I've had no luck so far. Ace of Sevens (talk) 22:22, 26 January 2008 (UTC)
replies: text: This article says that hardware sales of all formats (BD, HD, and dual) is less than 10% of SD. The numbers are hard to fathom though as NPD doesn't count the Xbox drive (which is a dedicated drive) nor does it count the PS3 (which might be used for BD playback) nor does it include Amazon, which sells a lot of HD DVD hardware. Also note that since late last year, several BD companies have been giving away free BD players with the purchase of a TV, and they count as "sales" (since they go through the register) so it's not really a true indicator of what "the market" is.

thread_title:  Recomend a new section for Retailer Support for the regions - US, UK, Japan, Australia 

message: I'm not sure if it would fit in this article or not, but is there a particular reason why both Blu-Ray and HD-DVD editions of films previously released to standard DVD often omit special features? I was quite disappointed to discover that the Blu-Ray edition of Resident Evil: Apocalypse omitted the gag reel included on the DVD release (as well as I think a couple of other features but I haven't been able to do a side-by-side comparison). In fact, when the first BR and HD-DVD discs came out, one of the criticisms was how they tended to be vanilla while the DVD had all the goodies. Is there a technological flaw preventing the two new formats from containing all the bonus features seen on DVD releases, or is there an issue with licensing. And if so, does one format have the edge over the other in that regard? 23skidoo (talk) 17:08, 3 February 2008 (UTC)
replies: text: As far as I know, the only technology-related issue that could be keeping bonus features included in SD DVD releases from appearing on HD formats could be storage size.  There are several occurrences of 480p video bonus features placed on high definition media.  It is more likely that studios are holding back features they intend to include on a later release of the same title.  Such practice is common by many studios' DVD releases, usually referred to as double dipping. 70.119.37.244 (talk) 20:48, 3 February 2008 (UTC)

They will all end up blue (well, I guess some of the smaller and independents might not, or might not be able to afford to) so when that happens we wont even need the pie chart anymore.

thread_title:  Studio Support Picture - Round 2 

message: It appears the last HD DVD exclusive company Weinstein has become Blu-ray exclusive, and so Weinstein needs to be turned blue in the Studio Support picture. Although they have not yet stated they are Blu-ray exclusive it is already clear they will not bring out any more HD DVD. 
Through the first several months of last year, Genius was releasing titles in HD DVD, but has stalled since then.
“Whether its Blu-ray or HD DVD…that was solved today that HD DVD backed out,” said Genius CEO Trevor Drinkwater during the company’s presentation at the Roth Capital Partners event. “Blu-ray is the last format in, and that has cleared the way for the industry to get aggressive around next generation DVD.”
A spokesman for Genius said there weren’t immediate plans for the company to specify its high-definition strategy. Drinkwater likewise did not detail upcoming Genius high-def releases during his speech.

text: I think the chart best represents what the studios are currently doing at present, so to the article best represents what is "currently" going on there is already a large paragraph within the Studio Support section about the past which already seems out of place and doesn't quite fit within the section - "These alliances have shifted over time. Prior to October 2005 and before the release of either format," I think another page or section should be created for how things were before the collapse of HD DVD. Yes the chart will be all Blue and disappear once all studios are exclusive but to have only the picture of how things were can be misleading to new readers to the article who would think there are still HD exclusive studios. So either 2 pictures [past & present], separate page or separate section outlining the studios previous stances.Denzelio (talk) 22:22, 25 February 2008 (UTC)

replies: text: As much as HDM (HD DVD vs. Blu-ray Disc) was a niche, downloading is even more so. One of the requirements of inclusion on Wikipedia is notability, and IMHO, download services aren't notable enough to warrant their inclusion in a comparison article (or rather, that such a comparison article even exist). If a downloading service should reach an installed base or a usage level that makes it notable and worthy of consideration, then yes, we can go from there. But I don't see that just yet, and would rather settle this article down around other high def optical media (which should be simpler to deal with than trying to force a comparison between a downloading service and an optical media format). —Locke Cole • t • c 04:38, 8 March 2008 (UTC)

message: The second paragraph doesn't seem to be very well written, nor make a great deal of sense (especially the first sentence "AVCHD could be one of the reasons for Blu-ray Disc format to win").  Unfortunately I am not knowledgeable on this topic, but I will at least have a go at improving it from a purely English language point of view. StarDelta (talk) 14:03, 4 May 2010 (UTC)
