5. The Inside

Basically there is nothing mystique about a DVD player. All you need is a DVD-ROM drive, power supply, controller and decompression chip and some software for the playback and menu functions.

The decoder chip is the Vaddis III from the video specialist Zoran. As you can easily see on the photo, Dolby Digital is supported in hardware (it's 5.1 as 6.1 devices are still very expensive).
