Video source isn't delivering the stream in the correct format-Skype

I downloaded latest version of Skype and I lost video in all other programs that use video .Uninstalling Skype did not help,video in my Yahoo messenger and my Windows Movie Maker still didn't work . I found and installed earlier version of Skype 3.8 . After that I started Windows Movie Maker ,clicked on "Capture from video device" . On next window I clicked "Configure" button ,than "Video Settings" button and changed Compression to RGB24 than Apply and my video was back on all programs that use video. Hopefully this will help you as well to solve problem with screwed up video after new installation of Skype.
