Nice work Wombler.
I have a few observations on the software. First, the trial is considerably less generous than that seen from Magic's main competitors. While five attempts may give you an idea of how the program works, it certainly doesn't give you enough time to fully explore all the options.
The second is, what is the possible use of a password on a copied dvd? I have to agree with your assessment of this option in the software. While it does offer something different, I can't see myself ever using it.
I would think that removing UOP's should be checked by default, and not left open.
And as someone who uses encoders rather than transcoders for compressing movies, I don't really see myself using this particular program, but it is encouraging that they have done some tweaking to this part of the program, and are giving acceptable results with difficult material.
