I spoke too soon. It gave me one you-tube video with sound, and then back to the silent treatment. I think I need to set the program as the default, and I haven't been able to do that. Most of the videos I can pretty much follow along without sound, though it does take away from the experience. I think Window media player is somehow messed up. Thanks for trying to help. I appreciate it.

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
