Worked on a strange one today. This movie would never open in the computer at work (either drive) Brought it home and it tryed to open but kept locking up the program, Fab Platium, in my newest machine. Put it in my old PC and it did get the movie open using Platium 4 Decrypter in my old HP drive. Every time it started copying, main movie or full disc, with or without pathplayer, it would stop at less than 1%. It has both full frame and widescreen verisons on the disc. I finally got it to copy the full frame movie only to the HD and it did burn to a disc. If you try the WS verison it locks up and stops. I sent the IFO files in to Fengtao, hope it helps. This is a new Sony disc, I did swap for another copy and it did the same thing.
After all this I've backed up 5 other movies on the machines that wouldn't do this movie without any problem, so it must be the Sony movie.
