<t>This seems like another ring protection similar to Laserlock and CD Ring Protect. Jackal or Reentrant will have to chime in here if they have ever dealt with that particular protection, and if there is a method of dumping it. I gave up trying to dump discs with these protections as the results ...

sarami, please remove this cab scanning stuff, this is out of scope for DIC. Please make a separate tool or make it off by default.

I've never had issues with it on CDs ...

That's weird, I was able to capture it, I sent you a log before but you said something about not being able to open it. Maybe its because I am using a USB adapter?

<t>OK, I was just curious actually if there was some miscommunication because of language differences. I'm going by what he said, I'll prod him to post here again.<br/>

Now that you have Bushound working, can you also analyze what Alcohol does with errors and DPM. Would be great to have all in ...

I'm curious if you misunderstood what RibShark was saying.

I verified that VOB Protect CD has illegal MSF, so these all need to be redumped without /sf
