I am trying to use cdrdao to read and backup my (legitimate) Playstation2 DVDs in Linux. I have tried two different DVD drives (a 3 year old Samsung and a brand new LG GSA-4163B) without success. I have tried cdrdao 1.1.9 and 1.2.0. I have tried the generic-mmc and the generic-mmc-raw drivers. I have tried all the options in the cdrdao README (e.g. --driver generic-mmc:0x3). I have even looked at the source code. Here is where it fails:
  // read disk toc length
  memset(cmd, 0, 10);
  cmd[0] = 0x43; // READ TOC
  cmd[2] = 2;
  cmd[6] = sessionNr;
  cmd[8] = 4;

  if (sendCmd(cmd, 10, NULL, 0, reqData, 4) != 0) {
    message(-2, "Cannot read disk toc.");
    return NULL;

A 'normal' DVD (e.g. the installation DVD that came with the drive) can be read fine (although it's mode 1). All of my PS2 disks fail (they are all mode 2 I think). I have included the output from one invocation below.

I did find that 'generic-mmc-raw:0x10000' gets rid of the first error ("ERROR: Cannot read disk toc.") but it still reverts to MODE 1 and then fails in the same way.

Is there anything else I can do to try and work out a fix? Perhaps what I am trying is no longer possible with cdrdao?
