camera video not playing wmp 10   

I have just acquired a Praktica DCZ6VR digital camera. It has a facility to 
take videos as do most digital cameras nowadays. So if I make a short video, 
I can replay it okay on my camera, but when I remove the memory card and load 
the files onto my computer, it saves it as a Windows media player file, which 
is correct. When I try to play the file, using Windows media player 10, it 
does not play back the file, but it does go through all the correct motions, 
with the slider at the bottom of the picture moving to the right as if it was 
playing the file, but the screen remains black. It is the same when using 
real player. I have tried this on a couple of other people's computers, and 
it works fine on their computers, one has Windows media player 9 installed, 
and the other has Windows media player 10 installed. I tried reinstalling the 
operating system, (Windows XP professional) on my computer, and with the 
reinstalled operating system, then it will play the file correctly, using my 
Windows media player 10. I have Norton ghost installed so I can return to my 
regular setup..... No problem. 
I have Windows XP professional. 1.5GB Ram 2.7GB processor. 
Does anybody have any ideas what the problem is please?

This group is the group for WMP for Mac actually. You might want to try
reposting in one of the regular WMp groups,
