a very long time ago I messed around with the PMM. it barely worked for me.
For me a deal breaker is the trailer or custom intro thing. I spent a few $'s on having custom intros made. I have not had an easy time playing the intro and then switching to the movie. I would assume that this can also me accomplished somehow with DVDLobby and scripting, but I have not played with it to know for sure.
I had requested many times for binner to add it to MyMovies, but that never happened, so I was hoping that this would be the answer.
