[MacDV] QuickTime Screen Size

We've discussed this before, but I'm still a little confused.

Full quality DV is 720 pixels by 480 pixels - a 3 to 2 aspect ratio. it 
seems to me that - when making a Quicktime movie - you would want to 
try to maintain that 3 to 2 ratio. Which would give you possible 
QuickTime screen sizes of 360 by 240, or 240 by 160. yet it seems like 
everybody recommends Quicktime screen sizes of 320 by 240 or 240 by 180 
- which are, however, 4 to 3 aspect ratios - matching the standard TV 
ratio.

Does QuickTime do something to the video during encoding to change the 
aspect ratio without squishing the people in the video?

Admittedly, if you export a QuickTime movie as full quality DV and play 
it in the QuickTime Player, the proportions look a little odd. Maybe 
full quality DV displays in the wrong proportion on a computer screen 
and QuickTime is just compensating.
