What time takes a backup / DiVX

I'm planning to get me a PS 2 (PAL) with Neo 2.2 + DVD Region X.

1. I was wondering how long it takes to make a backup of a PS2 game with a) clone cd b) cdrwin and which was the better way?

2. And what about these games on DVD, let's say a game is bigger than the max. available 700 MB on a CD, is it possible to split such games on several cds?

3. When I make me a backup of a a.) pal game b) ntsc game, will my console play it in b&w?

4. Bit off topic though, but will my ps2 or any dvd-player be able to play my DiVX movies?

5. Is there anything else I should know before I buy the PS 2, maybe wait for a better chip or expect any problems that might occur?

Thx in advance
