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.
