DVD vs. BD sales
You know what either this article, DVD-Video, or Blu-ray really lacks? A comparison table of sales charts between DVD and BD, both in the US/Canada and internationally. The German article has such a table, clearly showing that the sales of BDs hasn't even reached half that of DVDs in Germany yet, while the English articles only shily mention in passing that a.) according to Media Research Center, the rise of disk sales relative to each format's time of introduction is far lower with BD than it was with DVD, and b.) the only country where the BD is more successfull than the DVD so far is Japan. In the UK, sales of BDs are so desasterously low that the format is entirely dependent on dying video rental shops and mail-order rental in that country. All of which makes it seem like the actual format war nowadays is actually that between BD and DVD, and the above are good reasons to include such comparison charts in one or two of the three English-language articles. Since this article and DVD-Video are about DVD, their charts could have three colums: VHS | DVD | BD, to show the historic development since the late 1990. --79.242.203.134 (talk) 16:09, 8 June 2017 (UTC)
 * Sure, if there are solid references, and if it's updated when the refs come out with new data. Jeh (talk) 23:28, 4 March 2018 (UTC)

Binary prefixes and multiples
When a label on a DVD+R says "4.7 GB" that is an SI-style prefix. It means approximately 4,700,000,000 bytes. You will find this figure everywhere in media marketing. The tables in this article should follow those references, using "GB" in the column header and displaying numbers to be interpreted using the SI meaning of GB. I will make this change if there is no objection within a few days. Jeh (talk) 23:31, 4 March 2018 (UTC)
 * Do it! Note the capacity section says, "in the DVD realm, gigabyte and the symbol GB are usually used in the SI sense (i.e., 109, or 1,000,000,000 bytes)" so why use binary prefixes? I would have done it if I had the time.  Tom94022 (talk) 19:23, 20 March 2018 (UTC)
 * Absolutely, go ahead. Unreasonable binary prefixes are lame. --Zac67 (talk) 20:14, 20 March 2018 (UTC)
 * As often happens, I got distracted... but, it's done. Jeh (talk) 10:13, 14 September 2018 (UTC)
 * I just updated these changes. I'm assuming Jeh's numbers are all correct if they reference decimal prefixes, so I left them in place. But most of the table headers still used the binary prefixes, so I updated those headers to go along with the new decimal numbers. Stridskanin (talk) 02:13, 2 February 2019 (UTC)

Max minutes when burning DVD
Someone should add in the tables how many minutes are for each size of the disc when burning DVD to it. For example, the most standard disc of 4.7 GB can accept only about 60 minutes (even though it has a mark of 120 minutes) when burning it like DVD (with e.g. ImgBurn) for watching movies/series on a DVD player, PS2 etc. (this makes problems for movies because they are usually longer than 60 minutes; 4.7 GB disc is thus suitable only for series' episodes usually shorter than one hour). --5.43.74.138 (talk) 19:00, 20 June 2019 (UTC)
 * Unlike CDs, DVD Video can run at variable bitrates up to 10 Mbit/s. I think there's a low boundary as well but can't find that at the moment. So, the capacity of video that a DVD can hold depends on the encoded bitrate used by the recording device or the encoding software. --Zac67 (talk) 20:11, 20 June 2019 (UTC)

DVD may have come out a little earlier than 1995
I don't mean to use the talk page as a forum. But I've been learning for the past ten years that DVD might have begun as early as mid-August or September 1994 rather than early 1995. How can I find sources to prove this? Angela Maureen (talk) 06:38, 14 September 2018 (UTC)


 * It's highly doubtful that you will find any reliable sources to back that up, since the DVD specification wasn't even finalized until December of 1995; the first products didn't appear until late 1996. Certainly people were working on other designs of optical disks for video well before that, but that's beside the point for dates on DVD. Jeh (talk) 08:20, 14 September 2018 (UTC)


 * I have deleted the "dubious" tag you added to the 1995 date in the lede. The specification date of December 1995 and the product introduction date of late '96 are very well documented. There's nothing "dubious" about them. Perhaps you should go back to the people or places from whom you've been "learning for the past ten years" and ask what their sources were? At the Teahouse you wrote "There is likely evidence ..." well, where is it?


 * Or, you could start with the references we already have that support the current article, and work backward from those.


 * There is an amazing resource of archived consumer and professional electronics publications, going back many decades, at the American Radio History site. Have fun!


 * There may be ambiguity over the word "started". As described in DVD there were several "video on a disc" formats well before 1994. Video CD, for example. But that wasn't DVD. It could be argued that the DVD format was being "worked on" in 1994 or maybe even earlier; they were simply calling it MMCD. Or maybe it was the other group, the one that was calling their project SD. However, as described in that section, the formal spec for the "DVD format" wasn't agreed upon until late 1995, and it was a compromise between features of the MMCD and SD formats. It would be difficult to claim that development on DVD specifically had "started" when the specs of what was to be called "DVD" hadn't even been standardized. I believe the current material does address this.


 * Your section here though is titled "may have come out a little earlier than 1995" and the wording "come out" would refer to released products. Such a claim is flatly contradicted by well-documented product introduction dates. See for example https://lasvegassun.com/news/2011/jan/09/booms-and-busts-look-ces-checkered-history/ as a "popular press" source. Jeh (talk) 21:55, 25 September 2018 (UTC)


 * Apologies for a necromancy of this topic, but earliest mention of DVD I could find points to a January 1995 U.S. News web article right here, via Wayback. However, there may be references to MMCD as early as December 1994... TheBuddy92 (talk) 20:15, 17 January 2020 (UTC)
