You receive an error message or the file plays poorly when you import an .mpeg file that was created by using InterVideo Home Theater or WinDVD in Windows Movie Maker

When you use Microsoft Windows Movie Maker to import an .mpeg file that was created by using InterVideo Home Theater or InterVideo WinDVD, you may experience one or more of the following symptoms:

• You hear the sound, but the screen is black.
• The video quality is poor.
• You receive one of the following error messages:
  The file File_name.mpeg cannot be imported because the codec required to play the file is not installed on your computer. If you have already tried to download and install the codec, close and restart Windows Movie Maker, and then try to import the file again.
  File_name.mpeg could not be imported. Unspecified error
• When you right-click the timeline and then click Play Timeline, you receive the following error message:
  Too many interfaces. Can not load file

This problem occurs because the codec that was used to create the file is not compatible with Windows Movie Maker.
