Darren-- 07/29/14 If you'll put the DVD that has the NTHV in you computer's optical drive, then open the folder on the DVD, then click on one of the chapters, and you should hear me reading the New Testament, assuming your earphones or speakers are working. But if it asks you what app you want to use, choose Windows Media Player. Or, you can go to control panel, and click on "Default Programs." Click on "Associate a file type with a program." Scroll down to ".wma" and select Windows Media Player for .wma files. I used those same .wma files to burn myself a set of CD's that I use about every day to listen to the New Testament. F.H.
