How DVD Works.

A DVD is very similar to a CD, but it has a much larger data capacity. A standard DVD holds about seven times more data than a CD does. This huge capacity means that a DVD has enough room to store a full-length, MPEG-2-encoded movie, as well as a lot of other information.
Here are the typical contents of a DVD movie:
Up to 133 minutes of high-resolution video (The video compression ratio is typically 40:1 using MPEG-2 compression.)
DVD can also be used to store almost eight hours of CD-quality music per side.
The format offers many advantages over VHS tapes:
DVD picture quality is better, and many of DVDs have Dolby Digital or DTS sound, which is much closer to the sound you experience in a movie theater.
DVD players are compatible with audio CDs.

We most certainly have come a long way from compact dics and cassettes. I remember how I would go out to buy cassettes of my favorite new band while now, all you need to do is get the CD, LP, or even download it off iTunes.
