Blank Video

[Guest]

It has worked in the past on my machine but I now have no video. If I try and
watch a DVD or another video file previously saved I get a black screen. The
file plays and I can hear the audio but there is no video. This aplies to
windows media player and other players I have installed. I seem to have a
comprehensive set of video codecs installed but still no video?

Any ideas please.

What is the file extension of the file(s) that won't play.
