* The display duration for some DVD players may be set in this menu. The number of
photos that can be burned onto a CD or DVD depends on the sizes of the picture files.
You can also use the menu templates from the category "TV Showtime DVD" for the disc
types mini DVD and DVD. Each picture of a slideshow is then displayed in fullscreen on its
own menu page without having to playback the slideshow.
Digital Versatile Disc (DVD)
Quality
The exceptional color quality, image definition, and contrast of the DVD format are all well
known.
A resolution of 720 x 576 (PAL) and coded using MPEG-2, 25 pictures per second
produces very good results. The quantity of data is approx. 5 times as much as a VCD.
DVD size
DVDs look similar to CDs. The only visible difference is that double-sided DVDs have no
label. Otherwise, both formats have the same dimensions.
• Diameter: 12 cm, like a normal CD (there are also DVDs with a diameter of only 8 cm)
• Thickness: 1.2 mm, just like a normal CD
DVD media (overview)
The DVD does not differ outwardly from a conventional CD-ROM. Higher memory density
(up to 17 GB as opposed to 650-780 megabytes) results from the fact that information is
stored more densely (double-capacity) and that up to four layers can be used. In order to
be able to read the information, a special laser with modified wavelength is required.
Therefore, DVDs cannot be read using conventional CD-ROM drives.
