I have a series of videos that used to work in Windows media player. Now the video plays, but there is no sound. When I play these videos in VLC media player I get video and sound with no problems. When I play other videos with Windows media player there is sound as usual. What has happened and how do I get these particular videos to work in Windows media player again. I actually prefer VLC, but I don’t like when things do not work right, and I want to be sure there will be no future problems when I put these videos to DVD disk. Thank you in advance for any help.
