Hm. How do you decide what's right? Without a perfect circle
it's not so obvious. Also, how would DEI manage to squash the picture anyway?
Do telecines have free rescaling capabilities to any
degree you want?

I ALWAYS USED CIRCLES FOR SQUASHED PICTURE DETECTION.
Except for ALIBABA AND 40 CHOR, JIGAR, and may be 2 or 3 other (KNPH, KROADH), all other DEI anamorphic DVDs have squashed picture.
Yes, HDDCS, RANGEELA and HSSH all ,have squashed picture.
FIZA----------It is clear from the WIDESCREEN REVIEW that FIZA too is vertically squashed. As Ali remarked, “the original theatrical scope of Fiza is 2.39:1 according to the review – so how the video on the DVD is 2.55:1 (adding that they did notice the splice so hence it’s not over matted at all!)â€
I have seen FIZA songs in Mission Bollywood and they are vertically squashed. Look for “Maahi Maahi Re†song. Notice same arms when stretched horizontally or when upright, and you will see what I mean.
Note that the main (perhaps the only) reason for Anamorphic format is to get 33% extra resolution on wide-screen monitors. If anamorphic picture is 13% squashed, we get only 18% improvement (If you don’t agree with the numbers, see note below), instead of the required 33%. This 18% improvement over non_anamorphic comes with a penalty of watching a DISTORTED picture in 98% of the consumer displays.
2.66:1 instead of 2.35:1 implies a 13% vertical squash, whereas in most of my geometric comparisons, only 8-10% squash is mentioned. This is because I always used the measurement uncertainty to favour correct geometry. Quite likely, when I said 8% squashed, it really is 13%. Also If the original AR was 2.55:1 and 1.33:1 pixel doubled to 2.66:1 results in only 4% vertical squash, which is impossible to detect with any certainty. I think, 3 or 4 of DEI’s supposedly correct anamorphic DVDs are these 2.55:1 movies which may actually still be 4% squashed.
As Ali said in one of his postings, “even a monkey can fix itâ€, then why is it that the best Indian DVD maker has not fixed this problem for over one year now? May be it is deliberate. Deliberate, that is where my stated ratio ‘ 2.66:1 ’ has some significance which nobody has picked. I think, DEI is plainly shooting an uncorrected 1.33:1 picture and then just pixel doubling in the horizontal direction, giving a 2.66:1 aspect ratio (or may be, they have a 2:1 expansion lens only). Add a bit vertically and/ or crop a little from sides and you have a 2.5:1 aspect ratio, vertically squashed picture. This way they don’t need to buy the stretching lenses for cinemascope movies. If DEI uses this process, squashed picture problem will never be fixed.
P.S.
CALC. NOTE:
2.35:1 letterboxed picture = 272 lines
2.35:1 anamorphic = 363 lines (33% improvement over 272 lines)
2.35:1 squashed 13% (2.66:1)** = 321 lines (only 18% improvement over 272 lines)
2.35:1 stretched 13% = 410 lines (51% improvement over 272 lines)
