DVD Formats
At the first glance, the DVDs (Digital Versatile Disc) are not so different from a CD disc. Diameter and label printing are the same. However, the volume of data that can be recorded is quite different. Most common DVD applications are as follows:
- DVD-video One of the most common DVD format today. DVD includes mpeg 2 video images, up to 32 subtitles in different languages and up to 8 audios in different languages. It is also possible to use different camera angles and creation of different menus.
- DVD-ROM Suitable for using in computers as CD-ROM. Times higher data capacity is a major advantage. DVD-ROM is suitable for high-volume catalogues and computer games.
- Hybrid DVD DVD combining different DVD formats. For instance, Video+ROM
- DVD-Audio Rarely used audio disc with up to 5.1 channels

- DVD-9: 1-sided, 2-layered. Maximum possible data capacity 8.5 GB
- DVD-10: 2-sided, 2-layered. Maximum possible data capacity 9.4 GB. Disc label not printed. When used, must be turned around in the player.
