Wow! I saw some one online posted a few titles never heard of DEI
Do you mean, DEI authored DVDs that were not heard of before ?? Are these, or most of them, Progressive ?? Which movies ??
This, "Love In Tokyo" DVD is by Moserbaer.

Encoding is 30 fps Progressive but is not one film frame into one video frame (Orig film frames, 24 or 25 fps, have been thoroughly mixed up into 30fps video frames). It's field averaged. Not sure if it got 4% speed up in the process ??
Most of the NFDC DVDs released till now have a similar type of encoding. Read my post here:
viewtopic.php?f=1&t=12221&p=103721#p103715Its really puzzling as to whether this type of encoding is really progressive or not.
Most likely, as India is a 50 Hz country, mastering must have been at 25 frames per sec or 50 fields per sec. 25 frames per sec is Progressive encoding, 50 fields per sec is still interlaced but if it's 4% speed up, picture displays, or can be weaved back, like/ to a Progressive frame. Changing this 25 or 50 frames into 30 or 60 can be done
Either by:
Mixing up all the frames (all 30/ 60 frames will be blurry as they contain more than one film frame) and then make 25 frames out of it or 50 fields. This then can be a Progressive or interlaced encoding but the damage was already done in mixing up of film frames.
Or by:
Keeping all frames in tact but repeating every 5th frame. This is how some of EVP Hindi DVDs were encoded.
Or by:
Mixing up all frames at every stage or in one of the stages and then encode Progressive or interlaced. - - - -
It's conceivable to Force weave a video master, resulting in Combing, and then encode it Progressive which will always have that combing picture whether you watch it on Interlaced or Progressive display.
Basically, if you keep track of film frames and don't let the frames mix up, display frames will be original film frames. This does entail repeating of frames, every 4th or every 5th.
If the frames get mixed up while converting from 24 to 25 or from 24 to 30 or from 25 to 30, all video frames will be blurry.

Technically it's Progressive but made from a ruined copy.
