I copied the Blu Ray disc a third time. There is still no sound when I play it back on computer using Windows 7 Media Player. But there is sound when I play it back on the TV using Western Digital Media Player. Problem solved. Thanks for your help.

I converted a Blu Ray disc to mkv file. The picture quality is excellent but there is no sound on the movie. There is sound on the extras. It may be a DTS problem. I am using the Beta version. Any suggestions would be appreciated.
