Changes (by Carl Eugen Hoyos):

 * keywords:   => mov aspect
 * status:  new => closed
 * resolution:   => invalid

Comment:

 The mov file does not contain a pasp atom (that would contain an aspect
 ratio) and the display matrix in the tkhd atom is the identity matrix. The
 remaining question is if the identify matrix in the !QuickTime tkhd atom
 indicates no aspect ratio or an aspect ratio of 1:1.
