Help requested with VLC conversion of .mxg file

[mll]

Thanks very much for your help with this .mxg file conversion question....Does someone know proper VLC settings to convert .mxg file to either .mov or .avi file. VLC reads/plays test .mxg file, but fails to 'convert/save' to create .avi or .mov file. Receivef this error message: http://www.tejashummer.com/VLC_error.JPG. Must be a 'keystroke' problem on my part. Thanks very much for any advise on remedy. All the best. ... MLL
