I just downloaded the latest released version (184.108.40.206) and tried it out on "Invisible" yesterday. It did produce a viewable copy on my hard disk (using DVD Decrypter as the ripper) but I could not produce a usable disc. I tried Nero, Instant Copy from Pinnacle and DVD Shrink 3.2, but they all either made coasters or crashed. I went back to the forum and downloaded 220.127.116.11 Beta. This also produced a viewable image on the hard drive, and also caused Pinnacle to crash. But DVD Shrink liked what it saw, and made a perfect (4.7GB) backup of the double layer movie. I looked for some reference to Invisible on the forum but haven't seen it so far. I also noticed that the volume label on this movie DVD ended with "NNW1" the same as the volume label for "Howl's Moving Castle." I wonder if this is a sign that the disc carries ARccOS technology? In any case 18.104.22.168 seems to really do the trick. Thanks!
