Update file paths to movies in PowerPoint
I've created a PowerPoint presentation in my Windows 7 PC. I used a lot of avi video but when I added my PowerPoint presentation in my laptop (Windows XP) the videos are not working, it shows a black screen. All codecs are installed and also the video are working ok in media player. There is not a path issue because video are in same folder as the presentation.
My solution is to change .avi to .mpg (stupid solution but works) but I need to change the path of the video. A solution to delete the video and add it again its not good for me because for every video I have custom animations and custom thumbnails.
So maybe something to edit the link and change .avi to .mpg.
