@jkenzie (or anybody else who has PowerDVD): could you try the following:

Open the 001.fcl file in WinHex (make a backup first) and see if there are any random stuff in it (I suspect the bulk is random is it?) Now change one byte in that area and try if Power DVD will play a movie. And try changing the file at different places (but only change at most one byte compared the the backup) and see what happens.

This could pin-point the exact position of the Device Keys used. But its possible there is some kind of checksum which disables this technique. If it works all the time then I suspect there are no Device Keys in it at all.
