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.
So I suppose, you are championing the typical Indian mentality of catering to the lowest common denominator. Based on your logic, we should be prepared to be watching non-anamorphic Indian DVDs with mono sound, until the very last 4x3 tv incapable of a vertical squeeze mode exists. Which presumably would be for atleast another 10-15 yrs in a country like in India. Or better yet, they should be releasing the DVDs in Black & White, after all there are still quite a few of those around in India and as you must be well aware a B&W video is much better on a B&W tv, compared to colour video on a B&W tv. I suppose you must be a very happy man with the excrutiatingly loud 5.0 mono Indian DVDs which have audio mastered catering to the low end television sets in India.
Bottom line is, on a 19"-21" tv, the most common size of tvs in India, does it really matter about a few lines of resolution. I don't think so. Anyhow, without getting into the nitty gritty technical details, you really don't lose very much, if at all, with an anamorphic DVD on a 4x3 tv without vertical compression. That is simply because the non-anamorphic DVD has far less lines of resolution than the anamorphic DVD. Thus with an anamorphic dvd played on a 4x3 tv even without vertical compression, you still end up with approximately the same lines of resolution in the picture area, as you would get from a non-anamorphic DVD. The dropped lines are basically the ones that had been gained from the anamorphic transfer which utilizes the resolution of the entire 4x3 frame unlike the non-anamorphic DVD. Basically there is no real difference for the 4x3 tv without linear compression, the only difference being between losing the resolution at the time of transfer or losing it at the time of playback.
