Won't work.  The way you are calculating aspect ratio assumes square 
pixels (i.e. aspect of 1:1, or 1.0), whereas DVD/HDTV/TV use rectangular 
pixels.  In the case of DVD the aspect ratio of each pixel is 4:3 
(1.33), and for HDTV it is 16:9 (1.85).

If you work out the ratio you calculate you get 1.5 for DVD resolution 
images, quite a bit off of the 1.33 standard.  The HDTV is even more 
warped if you calculate the aspect ratio based on horizontal/vertical 
pixels.

It's irritating as hell - most computer media players don't play back 
the animation with non-square pixels, so it looks warped on the 
computer, but fine on the output...
