When trying to back this up, tried to rip to hard disc with one of my drives but I was told it wasn't ready even though looking at the status of the disc it seemed to be ready to go. I'm attaching a logfile and two screen captures: it seems it can't make up its mind whether there is structural copy protection or not, as you can see from the screen captures. The one where structural protection was detected was with AnyDVD in default; the other was with the I/O warning disabled and with search for updates disabled.
