Questions about DNAS, modchips, and DVD Drives.

[Cyber Akuma]

Ok, I have 3 questions

1. Does DNAS ban your system if you attempt to play online with a modchip on? Or does it just block it until you turn the modchip off?

2. I coudlent find info on the stickies, is there a webpage anywhere that tells me what mod options I have for my ps2? most of the newer modchips dont work with my version, I have a 30001-R with a serial of U0763989. I think its a V4, not sure.

3. I am worried about my DVD drive, it has never given me a dre but sometimes games take up to 10-20 seconds on the browser screen to boot. Would I be able to buy a replacement DVD drive for it should it go out? Since if I mod if and then it goes out I doubt sony will repair it. And how much would these drives cost?
