I recently discovered what i could only speculate is some kind of glitch in interactive player. I bought the HP4 movie and when to view some of the DVD-Rom features on the disc, but it said I had to install Interactive Player to view the content. at the same time, i have a VIDEO_TS folder for another movie on my hardrive. After installing the player, every time i went to open it, the welcome screen for the other movie would come up and i was able to watch the movie as if it were a dvd in my disc drive. any suggestions on why this would happen are welcomed.
