I've noticed recently that my dvd player will not recognize some discs,
including(gulp) my operating system reinstallation disc. I can think of only
two things that could have caused this error. One is that I recently played
around with new graphics card drivers for a computer game. The other is that
a while back I tried a free registry cleaner on my computer to fix errors and
improve performance. If either of these things was the cause, what can I do
about it? I am running Vista home premium if that is of any importance.
