Need help with viewing the saved avi file

Hi

I am a new solidworks flow simutation user. I was trying to do an external trasient analysis for a flow around a single cylinder. After finishing the run and creating a cut plot of the velocity contours, I recorded/saved the animation (as an avi file) for 10 seconds. When I play the animation in SolidWorks window, I can visualize the velocity contour. But when I try to play the saved avi animation file separately, its does not show anything; only a blank screen is seen although the video runs for whole 10 seconds . Can anyone suggest me how I can fix this problem so that I can save the animation with the velocoty contours? I need this avi file to add in a powerpoint presentation.

Thanks in advance.
