I don't use Windows, so I can't be sure, but I think I read somewhere you need 
to quote the path inside the string:

command "mediainfo \"C:\\folder1\\another folder\\file.mp4 \""

If you don't want have to escape the " inside the string, you can enclose it 
in single quotes, instead:

command 'mediainfo "C:\\folder1\\another folder\\file.mp4 "'

I hope this helps
