I have the Samrat/Music India release of Sangdil.

Running time of the DVD is 2hours 11mins. I see that there are YouTube uploads of the "Priya" release that have a running time of 2hours 15mins. The Priya version looks to be really bad quality. The Samrat very is quite bad, but not as bad a Priya. I would rate it as watchable. The print they have used is quite worn in places and there are cuts throughout. The songs seem to be intact (from memory). Sound quality of the disc is okay - not hollow sounding. The movie is great ... based on the book "Rebecca".
I never bought Tarana but I see a few versions on YouTube that look okay. I might try to seek Tarana out. While the movie's story is nothing great, the songs are outstanding!
