There appears to be a possible bug with the returned file name being given when AnyDVD fails to decrypt a VOB. I'm using the latest final version, 188.8.131.52, and came across a DVD where I could not fully extract VTS_01_2.VOB. When AnyDVD failed to decrypt the file, it returned that it failed on VTS_01_1.VOB. It seems the title stream where it's failing, the VTS has 3 VOB's: VTS_01_1.VOB, VTS_01_2.VOB, and VTS_01_3.VOB. I chose not to delete the files AnyDVD created. It created VTS_01_1.VOB, which was 0.99 GB, so that seems to have fully decrypted. VTS_01_2.VOB was only 525 MB, so it actually failed on VTS_01_2.VOB, but AnyDVD returned it failed on VTS_01_1. I don't know if this means there's a bug here, but it seems to be. With AnyDVD running, I tried copying and pasting VTS_01_1.VOB and VTS_01_2.VOB from the disc in File Explorer and it did fail to copy on VTS_01_2.VOB after successfully copying VTS_01_1.VOB. So, it seems that AnyDVD was returning it failed on VTS_01_1.VOB when VTS_01_1.VOB was actually successfully decrypted and AnyDVD should have been returning it failed on VTS_01_2.VOB. Thanks!
