Pyar Ka Mausam
Film 1969 CC = 4425 meters = 161 min
EROS DVD is PAL to NTSC field averaged, 153 min (159 min assuming 4% speedup)
Does not look like a big discrepancy but most likely what it might be, is in-excusable.
The most popular song of this film, Kishore Kumar version of Tum Bin Jaaoon Kahan is just 2 min in the beginning of the film and again a very slow sing later on, same lyrics. I never realized, it's just a 2 min version. How could it be just a 2 min version and still be the most popular from this film where a 7-8 min version of Mohd Rafi is also there.
There is an extra verse in HMV/ RPG audio album that's not in the DVD, 'Kitni Akeli Si Pehle Thi Yehi Duniya' that can account for the 2 min discrepancy. This verse is very relevant for that scene and makes me wonder, why did they (DVD makers or Film makers) remove this verse ??
