Hi, I was experimenting with these functions recently (trying to pass dvd or bluray stored on hard drive into MC16) and noticed that /DVDVideo {movie folder} launched the previously played (folder structure from within MC16) dvd (regardless of {movie folder} contents), and /Bluray {movie folder} gave a popup message saying no disk in drive. I don't think I made any config changes between trying the two command switches? So there may be a slight difference in how the switches are currently handled internally?
