Good print of IPZN is on youtube but can't find the exact link at the moment. The one I liked had SaReGaMa logo (stated as 720P) 153 min @ 4% speed-up comes to 159-160 min and looks ?? complete (including full songs). This 720P print beats the stated 1080P print by 21stCentury, which is also same content. At 160 min, this must be complete version ??.

I did d-load the SaReGaMa youtube video but can't find the same website at the moment. Will post it when I find it.
I have it's DVD and will check if really the youtube version is better. From memory, I think youtube version is better (Yes, SaReGaMa youtube is better).
---------------------------
Wow! What a film IPZN was. So colorful (with nice print, this film is the most colorful, as well as, most romantic of the times).

Update:
It's really confusing situation. The link I referred to that said 1080P print is not that good, was not the one I posted in that post. The one, I referred to as 1080P and bad is this one (even though it's the same 21 Century 1080P):

Moreover, perhaps it always was 480P SaReGaMa print that I mistakenly recalled as 720P.
In Summary:
BEST OF THE THREE PRINTS:
SaReGaMa 720P or 480P
Can't find exact same link, but found this 480P link, with similar PQ:

OK Print/ or as good as link above ??:
21 Century 1080P at

Bad Print even though it's 21 Century 1080P:

Looks like, it's very dynamic situation on internet or its results. In quest to find SaReGaMa 720P print, did not find that one but found many more postings, many of them as good as the one I mentioned as good 21 Century 1080P.

---------------------------------------
I mentioned 160 min film version (153 min @ 4% speed-up) in this 21 Century 1080P posting and it seems like complete film.
But, the film CC is 4474 meters, which is 173 min.

Out of so many postings (& bits and pieces) on the internet, one may find the missing 13 min ?? Yes, watching the 160 min versions, there are some loose ends not reaching their conclusion. The most important one being 'Jagdeep & his Mom' storyline.
---------------------------------------

If anyone has been following this post and its edits, you might have noticed that I flip-flopped whether SaReGaMa 480P print is better or the 21Century 1080P print. But now I after getting views from imaging experts, I 'm convinced too, that SaReGaMa 480P print is decidedly better and does have a WOW factor.

Dug up my Appolo DVD of Ishq Par Zor Nahin. Print is not as good as SaReGaMa 480P. Moreover, Appolo DVD is only 140 min.

INTAQAM:

Film 1979 CC Color Film, 4247 meters = 155 min
Bad print but almost complete are here:
https://www.youtube.com/watch?v=laDP-Tu8S9M (preferred one of these two)
https://www.youtube.com/watch?v=oF-QfzoeVTY (not the preferred one of these two)
Both are 149 min @ 4% speed-up (154-155 min film time)
(Despite full 155 min as per 1979 CC, there are discontinuities and loose ends. 1969 original version must be a bit longer)

A better print but just 2 hours is at:
https://www.youtube.com/watch?v=zfBK5Uj8I-E

Dug up my Appolo DVD and it's 116 min only. Print is similar to 2 hour version.

1969, original release must have been longer than 4247 meters 1979 version, as I already found, in the first 30-35 min of the film, 4 min 30 sec which is in DVD and not in the 1979 web version, which matches full 155 min 1979 CC. I'll try to compare the rest, later on.
