Any idea why DVD Decryptor fails when finding a BUP file?!

[harpe025]

I'm trying to copy a DVD-R to my hard drive that is unencrypted. When I run ISO-Write from the app, it always fails right after it finds VTS_01_0.BUP. Any ideas? I really want to back the DVD up to the hard drive and then burn new ones that way so I don't have to keep swapping discs all the time. I'll post the complete log file.

By the way, this happens on all DVD-R in this collection, it isn't just one DVD-R.
