Yeah that is what is so weird.
I can rip these discs with no errors (a few of them took a few tries to get a no errors tossed rip to succeed) but then I mount the protected UHD rip stored on the HD and use that as a source to try to create an unprotected UHD rip on the HD and then it tosses up sector errors!? Yeah using ANYDVDHD ripper both times.
I'm pretty surprised that it can somehow create a rip without tossing an error but then somehow the file on the hard drive has sector errors, seems very strange. (I'm not sure what sort of checksum system these discs use, but this seems kind of odd almost no matter what the story would be.)
I'll put up some logs tomorrow.
These are from SKywalker Box Set. TPM was a real mess of many, many sector errors tossed upon trying to make the unprotected from the protected rip. Same for AOTC. Both of them slowed quite a bit when making the original rips (And each took at least two tries.). ROTS rip attempt failed first time but appeared to go fast and smoothly the second time but even that when used as the sourced ended up tossing I think it was one set of sector errors when trying to make the unprotected. ANH failed the first time, but got it to work seemingly well the second time and this time, unlike with ROTS, the unprotected rip was made without tossing any errors. ESB failed the first time, but the second time seemed to go pretty smoothly and yet when making the unprotected from it still tossed a couple sector errors. Haven't gotten to trying the UHDs for the rest of the set yet.
