quick question -- if you have a conventional 4x3 TV which does not have a 16x9 or squeeze mode, would you still want to buy an anamorphic widescreen dvd or would you want to buy a non-anamorphic widescreen dvd of the same movie?
Anamorphic every time. TVs ability to have 16x9 or squeeze mode is irrelevant as the DVD player will take care of outputting the video is the right format.

If you have a 4x3 TV without an anamorphic mode or squeeze mode, you will have to set the dvd player to play at 4x3 mode. A player set to 4x3 mode will play an anamorphic dvd by deleting a line after every few lines from the anamorphic transfer uniformly from top to bottom -- doing so means that to fit the anamorphic source to a 4x3 display, the dvd player is eating lines (and therefore picture information) even from the "movie area".
However, if you have a 4x3 TV and a non-anamorphic widescreen DVD, the one plus of such a combo is that none of the information is deleted from within the movie area, if you know what I mean.
So on a 4x3-only TV, playing a non-anamorphic widescreen dvd gives you full information in the movie area (between the black bars) ---while--- playing an anamorphic dvd would give you lesser information in the movie area.
The above applies only to 4x3 TVs without squeeze or widescreen mode -- and true only for players set to play even anamorphic dvds at 4x3 mode.
Anamorphic picture on 4:3 screen:As I recall from some Yrs back when anamorphic mode was introduced for LDs/ DVDs (not sure if LDs gave first anam source or DVDs did ?? Anyway it was in when the DVDs came out and LDs started fading), sure there is minute disadvantage in PQ playing anamorphic source on 4:3 screen. It's not that dramatic as 33% degrade in PQ. I don't think every 4th line is deleted. Most likely it's a matrix conversion from 640 x 320 to 640 x 480 or similar/ vice-versa . Just like 640 x 480 signal displaying on 1280 x 1024 (assume it's a 1280 x 1024 native res screen) screen in screen native res of 1280 x 1024 or 800 x 600 or 1920 x 1080 or other. You hardly can see a diff in PQ. Secondly, 4:3 screens are mostly low res, you don't see any difference.
Technically, non-anam source is better for 4:3 TV but you don't see the difference, where as, you do see a difference in PQ on a 16:9 screen getting a anam signal.
So, I sure would pick a Anam DVD over non-anam DVD.
