A file with the MSDVD file extension is a Microsoft Windows DVD Maker project file. The MSDVD file format does not contain the actual video media. Therefore, to convert the MSDVD file to another video format, you need to do so on the computer on which the MSDVD file was made. The original video data can be retrieved from its original location, and the MSDVD project file converted to another video file type using Windows Movie Maker.
Open the Windows Movie Maker program.
Click the "File" option on the top taskbar, then click "Open." A File Open dialog box launches.
Navigate to and click on the MSDVD file. The project file opens in Windows Movie Maker.
Click the "File" option on the top taskbar, then click "Publish Movie."
Click "This Computer" and click the "Save as Type" drop-down box.
Click the desired video file format, such as the "AVI" format from the File Type list.
Click the "Next" button.
Click the "Publish To" folder icon and navigate to where you would like to save the converted and published movie.
Click "Next" and click "Publish."
Check the checkbox next to the "Play Movie When I Click Finish," if desired.
Click the "Finish" button. The MSDVD video project file is converted to the video file format you selected and saved to the designated location.
