[Ripping DRM'd dvds] anyone knows how to do it?

[Swax]

After long days, I am still stuck. It seems that my disk drive isn't flash-able...
Thank you to all the persons who tried to help me, I am grateful (even though I failed..)

From what I checked personally, there are 2 possible copy protection mechanisms in use. One is the old DVD CSS. Newer copy protection uses deliberate bad sectors at the beginning of the disc (I think that this is a new unnamed copy protection). Most tools were designed to bypass CSS, it uses a weak form of LFSR (linear-feedback shift register) driven stream cipher, but they have trouble with new copy protection. New copy protection is actually easier to bypass, even simple Linux tools like "dd" and "cat" will suffice. With the new copy protection DVD disc consists of 3 areas:

1. Short initial readable area
2. Short bad sector area, where most ripping tools fail, due to apparent read error
3. Long area with proper files / directories data

By trial and error (using binary search) you should find first sector of area 3. Then combine (with "cat" for example): area 1 + NUL byte padding of length of unreadable area 2 + area 3. This way you should obtain an ISO file equivalent to your disc as if it didn't have deliberate errors during pressing process.

I don't guarantee that this method will work as maybe now they invented a 3rd method as the previous 2 have long been cracked and exploited.

I can share an instruction with screenshots of how to rip, images + text might explain steps better than text above only

Hi, thx a lot. If I am not wrong it's pretty much the same process that we have discuss in PM... If not I would gladly try it...
