 	Analog video does not inherently have square pixels.  These are 
some of the standards-complient resolutions for an SD NTSC signal driving 
a 4:3 set:

720x480 (DVD)
704x480 (DVD)
480x480 (SVCD)
352x480 (DVD)

 	To make matters worse, there's no way to know if the video is 
supposed to be 4:3 or 16:9 in analog video.  It just depends on the set... 
google "anamorphic widescreen"
