I ripped a DVD using DVD Decrypter and it gave me a folder with files with .VOB extensions. I renamed these files giving them .MPEG extensions. When I play these files using Windows Media Player, they play back fine and in English. So then I imported them in to Vegas Movie Studio HD Platinum. The first two files played back in English. But the third file that I imported will only play back in Spanish! How do I get the third file to play back in English??
