Hi! I routinely use IsoBuster to check if a given CD or DVD can be read without problems in a given computer unit. For most CSS DVDs, the old DVD Decrypter suffices (I'm not a pirate, please read on). But some discs have an encryption scheme that confuses the soft into thinking it has tens of gigabytes by declaring fake repeated files. WinX has no problem, but unfortunately many read errors are concealed by this program. I do need to know if there were errors, no matter if they are unnoticeable in the ripped material. Can anybody suggest me a suitable program? NOTE: I have searched the Forum and found a couple threads closed due to piracy reasons. I have read the Rules, especially the "PIRACY AND LINKING TO PIRATED MATERIAL IS STRICTLY PROHIBITED". If I was a pirate I would stick to WinX and would not be writing this. I would be most happy with something like an IsoBuster that reads encrypted sectors but writes nothing to the hard disc (I have already contacted Peter, and he has no plans to add this feature). Thank you!
