Thanks everybody for your input.
I have made a new copy of the original DVD with DVD Shrink. Then I have created ISO with Image Classic Tool 0.93.1 and played it back from the hard drive (emulated with Virtual Daemon) with Media Player. The movie freezes again once Chapter 13 starts.
I have saved the log that Image Classic Tool had created and can post it if it might help but it?s huge (over 100 pages!). It mostly shows:

and so on and after this just a few lines

I also tried another way to burn. I burnt DVD from the same files but with Nero (without creating ISO) and also played it back with Media Player. There is no freeze at all!
When I play ISO with Media Player, I see 30 Chapters. When I play the movie (files) created with Nero, I see a different structure: there are no chapters but there are 7 Titles. The spot that freezes is somewhere in the middle of the Title and it runs without freezing.
I did my best to explain what I?ve got. Sorry if something is not clear. Thank you for your time!
Though Nero worked I cannot use it for burning as it cuts off the language options and leaves default Italian.
