It seems as though I was a little hastey thinking everything was fine. At first, after downloading the codecs, I could view videos without problem, but now I am having problems viewing an mpg. Although, I can view mpeg, avi and wmv. To make things more confusing, I had no trouble watching mpgs a couple of days ago. I watched one that I downloaded, but when I tried to watch it again a few days later, I got "cannot open" or something of that nature. What could have changed in the last couple of days that would not allow me to view an mpg, but still mpeg, avi and wmv? When I view the videos I can watch, they open in media player classic. I also have windows media player 10 installed.
