I just sent this to Apple Feedback but would like to submit it to MacRumor readers as it is a real bother that Apple could fix. Write Apple and ask them to fix this.
"It is completely bogus and an infringement on my rights to control my viewing experience that the DVD Player does not let me skip forward over previews or other parts of a movie that I don't want to see. I know you're going to say something lame like "but that is how the DVD is setup and it has nothing to do with the DVD Player software." WRONG. You can circumvent the publisher's locks and just ignore them. Let the viewer always skip forward, fast forward, menu, etc. The publisher should not be able to force the previews on the viewer. If I want to skip forward to the real movie I should be able to do so."
