A few years ago I played a dvd set in my computer by simply clicking on the drive. A few weeks ago I tried the same thing, and the InterActual player came up but it would only play the video, not the audio. I posted this problem and was advised to download the VLC media play, which I did, and it worked fine. Then I tried to watch the second season of the series, and the main menu is fine (both audio & video) but when I click on the episodes, I only get the audio. I retried a season 1 disc and it works fine. I also tried a disk from each set in the InterActual player, but only get the video (even at the main menu). What can I do to get this problem corrected?
