Are you referring to stamped discs, or to DVD-Rs for Authoring use (as opposed to DVD-Rs for General use)? Stamped discs can be manufactured by any replication house if you have the data (and the money). Authoring DVD-R equipment and media is out there (they use a different writing laser wavelength from General use discs) but both the drives and the media are rather hard to find and also extremely expensive. A feature that I wrote entitled "Burner Basics," which ran in the April 2003 and Winter 2003 issues (you can read it online here with a Club Vid password, which you can find in the upper right-hand corner of the current issue's table of contents) may help you to understand some of the terms (although it's slightly dated, considering that you can now get 8X burners--and we saw an announcement today for a 12X burner). -Charles Fulton, Associate Editor, Videomaker Magazine

The commercial DVDs you refer to are the 'stamped' discs that I referred to. A lot of it has to do with the reflectivity of the media. Discs recorded on a computer burner are not as reflective as stamped discs (that is to say, there's less difference between the lands and pits that the player's optical system reads). Later-model DVD players can cope more easily with discs that were burned in computers or set-top DVD recorders, not only because they have more refined optical systems, but also because their firmware is also much more refined as well. -Charles Fulton, Associate Editor, Videomaker Magazine

I wonder if you are talking about dual layer, or DVD-9, disks. Currently, we have only DVD-5 single layer capabilities in DVD+/-R and RW. However, later this year, the first consumer dual layer DVD burners may be out. They will double the capacity (and playing time) of current DVDR from 4.7GB to 9.4GB. That will mean you can have longer playing time, higher MPEG2 quality, or some combination of both.

Expect the first units to be expensive. They will be, as will the first blank dual layer DVDs.

Re-read what Charlie said. Anybody can get a commercial quality dvd if they're willing to spend the money to get stamped dvds. Costs a lot!

There are all sorts of new media coming out for dvd. But it's the same old problem of yesteryear - Beta vs. VHS. No one can agree because of who's patent is going to prevail. This is a BIG BUCKS issue!

Sony announced the first Dual Layer DVD burner... http://www.digitalvideoediting.com/2004/03_mar/news/e3jpa3wb.htm

It can hold 8.5gb of data.

The new burners will debut with an initial DVD+R DL recording speed of 2.4X. They will also feature up to 8X DVD+/-R, 4X DVD+/-RW, 40X CD-R and 24X CD-RW recording, providing users with double layer, dual format, and high-speed burning all in one drive.

The new drives are expected to start shipping by the end of the second quarter at an estimated selling price of $230 for the internal DRU-700A and $330 for the external DRX-700UL.

There's everything you need to know!
