MacTypes::Alias.path(...) creates a new Alias object. The MacTypes 
module is discussed in more detail in the appscript documentation.

QTP's 'open' command returns an array of references to the newly opened 
movies, in this case [app('QuickTime Player').movies['some file']]. 
However, we just want the first item in that array so we call its #[] 
method.

HTH

has

p.s. The equivalent line in AppleScript would read:

    set theMovie to item 1 of (open alias "HD:path:to:your file.mp3")

except that AppleScript uses an HFS path string rather than a POSIX one 
for legacy reasons.
