Beginners will be very confused.
Experts will laugh.

We can summarize DVD movie copying as follows:

1. With current technology it is impossible to make an exact copy of most, if not all, commercial movies. Any copy software that claims 1-to-1 copying is misleading.

Reasons: (a). Almost all movies are encrypted by CSS. The encryption key is encrypted and stored in a special sector on the DVD. All blank DVD media have this sector pre-written in factory. No way to copy the key onto a blank DVD. So in order to copy a movie, you must decrypt it, or DeCSS it.

(b). Almost all modern movies are dual layer DVDs (DVD-9) of 9GB. All current DVD burner/media are single layer (DVD-5) of 4.5GB. So you see you can never make an exact copy - at least before dual layer burner/media is available. If you want to copy a movie to one DVD disk, you must compress it (in laymen's term), or decode and encode it again with a different bitrate (in pro's term).

2. How to copy a DVD? You only need one piece of software: DVDXcopy (the cheapest express edition is good enough). It does the four things: DeCSS, decode, encode and burning. It does the first three things in step 1: it reads the DVD and creates tracks on harddisk. Then you insert a blank dvd and it does step 2: burning the tracks onto the blank. That's it. You only need to hit one button, and wait to see DVDXcopy do everything.

Because encoding is very CPU intensive, you'd better have a CPU at least 2GB P4.
