Thanks for the feedback. For the script I've produced, it will help if I can preset about six very important preference options in VLC. For instance, the playlist window needs to be visible when a group of movies is playing to keep track of where the current movie is playing. If black screens is enabled, it blacks out the primary monitor (video playing on the second monitor). I don't absolutely need it to do this, just trying to spiff up the app a little. Since I now know that I can't script the preferences in VLC, I can abandon that idea.
And, this is just a stop gab solution while I develop a xojo app.
