I have a DVD and when I put it into the computer a window does not pop up to let me play it. When I find the file in my computer it leads me to this PowerDVD program which, in it, when I press play, a box pops up which makes some copyright announcement. Then the DVD does not play. If I press play again, the same thing happens. The movie does not show up when I open media player. It is not the DVD because I tried it with a couple of DVDs. Why is this happening?
