When the subject behavior occurs, you may or may not receive one of the following messages:
Moviemk has caused an error in KERNEL32.DLL. Moviemk will now close.
Moviemk has caused an error in DIVXAF.AX. Moviemk will now close.
This problem occurs because Windows Movie Maker conflicts with the divxaf.ax codec.
To fix this problem:
1. Open a CMD.exe prompt.
2. Type Rename %SystemRoot%\System32\divxaf.ax divxaf.old and press Enter.
